Calmodulin-3 (CALM3)

The protein contains 149 amino acids for an estimated molecular weight of 16838 Da.

 

Calmodulin mediates the control of a large number of enzymes, ion channels, aquaporins and other proteins through calcium-binding. Is a regulator of voltage-dependent L-type calcium channels (PubMed:31454269). Among the enzymes to be stimulated by the calmodulin-calcium complex are a number of protein kinases and phosphatases. Together with CCP110 and centrin, is involved in a genetic pathway that regulates the centrosome cycle and progression through cytokinesis. (updated: Oct. 7, 2020)

CLONING

Fischer et al. (1988) cloned CALM3 from human brain and teratoma cDNA libraries. CALM3 is identical in amino acid sequence to CALM1 (114180) and CALM2 (114182), but within the coding regions, CALM3 shares only 82% and 81% nucleotide identity with CALM1 and CALM2, respectively. The untranslated regions contain no significant homologies. Using an N-terminal sequence to probe a Northern blot, Fischer et al. (1988) detected 0.8- and 2.3-kb transcripts in fibroblast, erythroleukemia, and teratoma cell lines. Only the 2.3-kb transcript was revealed with a C-terminal probe, suggesting use of an alternate polyadenylation signal. Toutenhoofd et al. (1998) measured the mRNA abundance and transcriptional activity of the 3 CALM genes in proliferating human teratoma cells. All 5 possible mRNA transcripts were detected in these cells, with highest abundance of CALM3. CALM3 was 5-fold more actively transcribed than CALM1 and CALM2.

GENE STRUCTURE

Fischer et al. (1988) determined that the CALM3 gene contains 6 exons. Koller and Strehler (1993) determined that the 5-prime flanking region of CALM3 is GC rich and contains a canonical CAAT box but no TATA box. There are several clustered SP1 (189906)-binding sites and 7 AGGA elements, which are found in genes encoding Ca(2+)-binding proteins. Using a promoter-reporter construct transfected into several cell lines, Koller and Strehler (1993) found that CALM3 promoter activity was neither cell type nor species specific.

MAPPING

McPherson et al. (1991) assigned the CALM3 gene to chromosome 19 by study of somatic cell hybrids. By PCR-based amplification of CALM3-specific sequences using DNA from human/hamster cell hybrids as template, Berchtold et al. (1993) confirmed the assignment to chromosome 19 and regionalized the gene to 19q13.2-q13.3 by in situ hybridization. ... More on the omim web site
