Anti-MTA2/PID Picoband® Antibody

Metastasis-associated protein MTA2 is a protein that in humans is encoded by the MTA2 gene. It is mapped to 11q12.3. This gene encodes a protein that has been identified as a component of NuRD, a nucleosome remodeling deacetylase complex identified in the nucleus of human cells. It shows a very broad expression pattern and is strongly expressed in many tissues. It may represent one member of a small gene family that encode different but related proteins involved either ly or inly in transcriptional regulation. Their in effects on transcriptional regulation may include chromatin remodeling. It is closely related to another member of this family, a protein that has been correlated with the metastatic potential of certain carcinomas. These two proteins are so closely related that they share the same types of domains. These domains include two DNA binding domains, a dimerization domain, and a domain commonly found in proteins that methylate DNA. One of the proteins known to be a target protein for this gene product is p53. Deacetylation of p53 is correlated with a loss of growth inhibition in transformed cells supporting a connection between these gene family members and metastasis.

May be involved in the regulation of gene expression as repressor and activator. The repression might be related to covalent modification of histone proteins.
