The Tcap protein appeared in the sarcomeric Z disc, and reduction of Tcap resulted in muscular dystrophy-like phenotypes including deformed muscle structure and impaired swimming ability. A defective interaction between the sarcomere and plasma membrane was detected, which was further underscored by the disrupted development of the T-tubule system. Zebrafish tcap exhibited a variable expression pattern during somitogenesis. The variable expression was inducible by stretch force, and the expression level of Tcap was negatively regulated by integrin-link kinase (ILK; <a href="/entry/602366">602366</a>), a protein kinase that is involved in stretch sensing signaling.

<span class="mim-text-font">
<p>TCAP is a sarcomeric protein found exclusively in striated and cardiac muscle, where it localizes to the periphery of Z discs that define the border of the sarcomere and serve as both a structural anchor and a signaling center. TCAP glues 2 parallel titin (TTN; 188840) within the same sarcomere by directly binding to the N-terminal Z1Z2 domain of titin in a palindromic arrangement, which dramatically increases the mechanical resistance ability of titin (summary by Zhang et al., 2009). </p>

<strong>Cloning and Expression</strong>

<span class="mim-text-font">
<p>By PCR of a human skeletal muscle cDNA library, Valle et al. (1997) cloned TCAP, which they called telethonin. The deduced 197-amino acid protein has a calculated molecular mass of 19 kD. Northern blot analysis of human tissues detected expression in skeletal and heart muscle only, which was confirmed by RT-PCR analysis. Immunofluorescence analysis of human skeletal muscle showed a banded pattern for TCAP that overlapped with myosin (see 160730) and alternated with actin (see 102610). </p>

<strong>Biochemical Features</strong>

<span class="mim-text-font">
<p>Using x-ray crystallography, Zou et al. (2006) showed how the amino terminus of the longest filament component in the Z disc of muscle, the giant muscle protein titin, is assembled into an antiparallel (2:1) sandwich complex by the Z disc ligand telethonin. The pseudosymmetric structure of telethonin mediates a unique palindromic arrangement of 2 titin filaments, a type of molecular assembly previously found only in protein-DNA complexes. Zou et al. (2006) confirmed its unique architecture in vivo by protein complementation assays, and in vitro by experiments using fluorescence resonance energy transfer. Zou et al. (2006) proposed a model that provides a molecular paradigm of how major sarcomeric filaments are crosslinked, anchored, and aligned within complex cytoskeletal networks. </p>

<p>Zhang et al. (2009) cloned tcap in zebrafish and showed that it is functionally conserved. The Tcap protein appeared in the sarcomeric Z disc, and reduction of Tcap resulted in muscular dystrophy-like phenotypes including deformed muscle structure and impaired swimming ability. A defective interaction between the sarcomere and plasma membrane was detected, which was further underscored by the disrupted development of the T-tubule system. Zebrafish tcap exhibited a variable expression pattern during somitogenesis. The variable expression was inducible by stretch force, and the expression level of Tcap was negatively regulated by integrin-link kinase (ILK; 602366), a protein kinase that is involved in stretch sensing signaling. The authors suggested that the pathogenesis in LGMD2G may be due to a disruption of sarcomere-tubular interaction, but not of sarcomere assembly per se. Zhang et al. (2009) hypothesized that the transcription level of TCAP may be regulated by the stretch force to ensure proper sarcomere-membrane interaction in striated muscle. </p><p>Markert et al. (2010) generated knockout mice carrying a null mutation in the Tcap gene and described skeletal muscle function in 4- and 12-month-old affected mice. Muscle histology of Tcap-null mice revealed abnormal myofiber size variation with central nucleation, similar to findings in the muscles of LGMD2G patients. An analysis of a Tcap binding protein, myostatin (MSTN; 601788), showed that deletion of Tcap was accompanied by increased protein levels of myostatin. The Tcap-null mice exhibited a decline in the ability to maintain balance on a rotating rod, relative to wildtype controls. No differences were detected in force or fatigue assays of isolated extensor digitorum longus or soleus muscles. </p><p>Ibrahim et al. (2013) found that, at 3 months of age, T-tubule density appeared normal in isolated Tcap -/- mouse cardiomyocytes, but that there were isolated T-tubule defects and minor changes in calcium handling. By 8 months of age, Tcap -/- cardiomyocytes showed progressive loss of T-tubules, remodeling of the cell surface, and prolonged and dysynchronous calcium transients. Tcap -/- mice were more sensitive than wildtype to chronic mechanical overload due to thoracic aortic constriction, with increased calcium spark frequency, significantly greater loss of T-tubules, and greater deterioration in T-tubule regularity. Ibrahim et al. (2013) concluded that TCAP is a load-dependent regulator of T-tubule structure and function in the heart. </p>

<p>In a 65-year-old Caucasian woman who was diagnosed with hypertrophic cardiomyopathy-25 (CMH25; 607487) at 44 years of age, Bos et al. (2006) identified heterozygosity for an arg70-to-trp (R70W) substitution in the TCAP gene that was not found in 100 Caucasian or 100 black controls. The patient had massive hypertrophy, with a maximum left ventricular wall thickness of 46 mm. Family history included CMH but not sudden cardiac death. Reporting on this patient, Theis et al. (2006) observed that she exhibited a sigmoid septal shape. </p>

To ensure long-term funding for the OMIM project, we have diversified
our revenue stream. We are determined to keep this website freely
accessible. Unfortunately, it is not free to produce. Expert curators
review the literature and organize it to facilitate your work. Over 90%
of the OMIM's operating expenses go to salary support for MD and PhD
science writers and biocurators. Please join your colleagues by making a
donation now and again in the future. Donations are an important
component of our efforts to ensure long-term funding to provide you the
information that you need at your fingertips.
