Summary: Enables several functions, including actin monomer binding activity; transcription cis-regulatory region binding activity; and transcription coactivator activity. Involved in actin cytoskeleton organization and positive regulation of transcription by RNA polymerase II. Acts upstream of or within negative regulation of apoptotic process; nervous system development; and positive regulation of DNA-templated transcription. Located in cytoplasm and nucleus. Is expressed in several structures, including early conceptus; epithelium; gonad; skeletal muscle; and telencephalon. Human ortholog(s) of this gene implicated in acute megakaryocytic leukemia and immunodeficiency 66. Orthologous to human MRTFA (myocardin related transcription factor A).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
