Homo sapiens

Also known as MLC-B; MRLC2

Gene ID: 103910 | Gene type: protein coding

About MYL12B

Cytogenetic location: 18p11.31 Genomic coordinates (GRCh38): 18:3,262,133-3,278,461 (from NCBI)

This gene has 5 transcripts (splice variants), 206 orthologues and 7 paralogues. Ubiquitous expression in colon (RPKM 243.9), lung (RPKM 208.5) and 25 other tissues.

Summary

The activity of nonmuscle Myosin II (see MYH9; MIM 160775) is regulated by phosphorylation of a regulatory light chain, such as MRLC2. This phosphorylation results in higher MgATPase activity and the assembly of Myosin II filaments (Iwasaki et al., 2001 [PubMed 11942626]).[supplied by OMIM, Mar 2008]
