<p>The PRKACB gene encodes a catalytic subunit of cAMP-dependent protein kinase (PKA), a tetrameric holoenzyme composed of 2 catalytic and 2 regulatory subunits (summary by Soberg et al., 2017). Other catalytic subunits are encoded by PRKACA (601639) and PRKACG (176893). </p>

<p>Soberg et al. (2017) stated that the main splice variant of human PRKACB, C-beta-1, is a 350-residue protein with 93% sequence identity to C-alpha-1, encoded by PRKACA. </p>

<strong>Gene Structure</strong>
</span>
</h4>

<span class="mim-text-font">
<p>Soberg et al. (2017) stated that the PRKACB gene has 4 alternative 5-prime exons, a cassette of short exons denoted a, b, and c, and nine 3-prime exons (2 through 10). Alternative use of exons 5-prime to exon 2 of PRKACB gives rise to at least 10 different catalytically active C-beta proteins. Exons 2 through 10 are expressed and translated in all known catalytically active C-beta protein isoforms. The intron-exon structure of exons 2 through 10 is conserved throughout vertebrate evolution. </p>

<p>Berube et al. (1991) assigned the catalytic subunit C-beta of PKA to human chromosome 1 by Southern blot analysis of somatic cell hybrids.

(1992).) </p><p>Stumpf (2020) mapped the PRKACB gene to chromosome 1p31.1 based on an alignment of the PRKACB sequence (GenBank BC016285) with the genomic sequence (GRCh38).</p>

<p>In 4 unrelated probands with cardioacrofacial dysplasia (CAFD2; 619143), Palencia-Campos et al. (2020) identified heterozygosity for de novo missense mutations in the PRKACB gene (601639.0001-601639.0004) that were not found in the gnomAD database. Functional analysis demonstrated that the mutant PKA holoenzymes are more sensitive to activation by cAMP than wildtype proteins. In addition, the variants inhibited hedgehog (see 600725) signaling, which the authors suggested as an underlying mechanism for the observed developmental defects. </p>

<p>In an 18-year-old Danish woman (P4) with cardioacrofacial dysplasia (CAFD2; 619143), Palencia-Campos et al. (2020) identified heterozygosity for a de novo c.703G-C transversion (c.703G-C, NM_002731.3) in the PRKACB gene, resulting in a gly235-to-arg (G235R) substitution at a highly conserved residue at a tethering surface that interacts with regulatory proteins. The mutation was not found in the gnomAD database. Bioluminescence resonance energy transfer analysis showed a dramatic increase in sensitivity to cAMP with the mutant holoenzyme compared to the wildtype PKA holoenzyme, and PepTag assay in transfected HEK293 cells showed increased kinase activity with the G235R mutant at low cAMP concentrations compared to wildtype protein. Analysis of hedgehog (see 600725) pathway signaling in retrotransduced NIH 3T3 cells after stimulation with the SMO (601500) agonist SAG revealed that the G235R mutant impairs SAG-mediated inactivation of PKA. </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.
