The mutation, which was identified by whole-genome sequencing, segregated with all 29 affected individuals in the family and was not present in 20 unaffected relatives. The mutation was not present in the dbSNP (build 135), 1000 Genomes Project, or Exome Variant Server databases, or in over 200 Spanish control alleles. Analysis of patient skeletal muscle cells showed that the mutant mRNA was expressed along with the wildtype protein.

<p>Using the RS domain of ASF/SF2 (SFRS1; 600812) as bait in a yeast 2-hybrid screen, followed by screening a HeLa cell cDNA library, Kataoka et al. (1999) cloned TNPO3, which they designated TRNSR. The deduced 975-amino acid protein has a calculated molecular mass of 109.8 kD. It shows significant similarity to other importin-beta/transportin family members (e.g., TNPO1, 602901), including a region required for RanGTP (see RAN; 601179) binding. </p><p>By yeast 2-hybrid analysis using the RS domain of the E2 protein of human papillomavirus (HPV)-5 as bait, Lai et al. (2000) cloned a TNPO3 splice variant, TRNSR2, from a HeLa cell cDNA library. The deduced 923-amino acid TRNSR2 protein lacks 2 regions of about 30 amino acids each found in the TRNSR protein identified by Kataoka et al. (1999). Northern blot analysis detected ubiquitous expression of a 4.5-kb transcript, with highest expression in testis. Epitope-tagged TRNSR2 localized throughout transfected HeLa cells, but a mutant lacking the N-terminal region colocalized with splicing factor SC35 (SFRS2; 600813) in nuclear speckles. </p>

<strong>Gene Function</strong>

<span class="mim-text-font">
<p>Using in vitro binding assays, Kataoka et al. (1999) found that TRNSR bound the RS domains of ASF/SF2 and SC35 directly, but it did not interact with other protein domains examined. A Ran mutant mimicking RanGTP, which promotes dissociation of import receptor-cargo complexes, abolished binding of TRNSR to RS domains. In an in vitro import assay, TRNSR efficiently imported the RS domains of ASF/SF2 and SC35 into the nucleus in an ATP- and RanGDP-dependent manner. Far Western blot analysis showed that TRNSR bound several proteins within an SR protein fraction purified from HeLa nuclear extracts. </p><p>Using yeast 2-hybrid analysis, Lai et al. (2000) showed that TRNSR2 interacted with the RS domain in the hinge region of HPV-5 E2. The C-terminal 400 amino acids of TRNSR2 also interacted with ASF/SF2, SC35, and TRA2-beta (SFRS10; 602719). Mutation analysis confirmed that TRNSR2 interacted with the N-terminal RS domain of TRA2-beta, but not with the RNA-binding domains of ASF and TRA2-beta. In vitro pull-down assays revealed that only ASF containing phosphorylated RS domains interacted with TRNSR2 in HeLa cell extracts. Lai et al. (2000) concluded that TRNSR2 has a role in cellular trafficking of phosphorylated SR proteins. </p><p>Using a large-scale small interfering RNA screen to identify host factors required by human immunodeficiency virus (HIV)-1 (see 609423), Brass et al. (2008) identified more than 250 HIV-dependency factors (HDFs), 79 of which showed significantly higher expression in immune tissues compared with other tissues. Depletion of the HDF TNPO3, a karyopherin, resulted in HIV inhibition after reverse transcription, but before integration. Brass et al. (2008) proposed that targeting of HDFs essential for the viral cycle but not critical for the host may avoid drug resistance due to viral diversity and escape mutation. </p>

(2013) identified a heterozygous c.2453G-A transition in exon 21 of the TNPO3 gene, resulting in an arg818-to-pro (R818P) substitution at a highly conserved residue. The mutation was not present in the dbSNP (build 137), 1000 Genomes Project, or Exome Variant Server databases, in 150 in-house control exomes, or in the patient's unaffected sister. Functional studies of the R818P variant were not performed. </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.
