Summary
Enables DNA-binding transcription factor activity; actin binding activity; and transcription coactivator activity. Involved in positive regulation of transcription by RNA polymerase II. Acts upstream of or within several processes, including circulatory system development; liver development; and nervous system development. Located in cytoplasm. Is expressed in several structures, including cardiovascular system; central nervous system; genitourinary system; intestine wall; and lung. Orthologous to human MRTFB (myocardin related transcription factor B). [provided by Alliance of Genome Resources, Nov 2024]
Expression
Ubiquitous expression in frontal lobe adult (RPKM 9.3), cortex adult (RPKM 9.3) and 28 other tissues See more

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.
