Human Gene MYL12A (uc002klr.3) Description and Page Index
  Description: Homo sapiens myosin, light chain 12A, regulatory, non-sarcomeric (MYL12A), mRNA.
RefSeq Summary (NM_006471): This gene encodes a nonsarcomeric myosin regulatory light chain. This protein is activated by phosphorylation and regulates smooth muscle and non-muscle cell contraction. This protein may also be involved in DNA damage repair by sequestering the transcriptional regulator apoptosis-antagonizing transcription factor (AATF)/Che-1 which functions as a repressor of p53-driven apoptosis. Alternate splicing results in multiple transcript variants. A pseudogene of this gene is found on chromosome 8.[provided by RefSeq, Dec 2014].

DESCRIPTION: RecName: Full=Myosin regulatory light chain 12A; AltName: Full=MLC-2B; AltName: Full=Myosin RLC; AltName: Full=Myosin regulatory light chain 2, nonsarcomeric; AltName: Full=Myosin regulatory light chain MRLC3;
FUNCTION: Myosin regulatory subunit that plays an important role in regulation of both smooth muscle and nonmuscle cell contractile activity via its phosphorylation. Implicated in cytokinesis, receptor capping, and cell locomotion (By similarity).
SUBUNIT: Myosin is a hexamer of 2 heavy chains and 4 light chains.
PTM: Phosphorylation increases the actin-activated myosin ATPase activity and thereby regulates the contractile activity. It is required to generate the driving force in the migration of the cells but not necessary for localization of myosin-2 at the leading edge (By similarity).
MISCELLANEOUS: This chain binds calcium.
SIMILARITY: Contains 3 EF-hand domains.

ModBase Predicted Comparative 3D Structure on P19105
The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
