Gene: MRTFA (myocardin related transcription factor A) Homo sapiens
Symbol: MRTFA
Name: myocardin related transcription factor A
Description: Exhibits actin binding activity and leucine zipper domain binding activity. Involved in positive regulation of transcription via serum response element binding activity; smooth muscle cell differentiation; and wound healing, spreading of cells. Localizes to cytosol and nucleoplasm. Implicated in megakaryocytic leukemia.
Type: protein-coding
RefSeq Status: REVIEWED
Also known as: basic, SAP and coiled-coil domain; BSAC; MAL; megakaryoblastic leukemia (translocation) 1; megakaryoblastic leukemia 1 protein; megakaryocytic acute leukemia protein; MKL; MKL/myocardin-like protein 1; MKL1; Mkl1 variant 1 Mkl1_S; MRTF-A; myocardin-related transcription factor A; RBM15/MKL1 fusion; RNA-binding motif protein 15/megakaryoblastic leukemia-1 fusion protein

NCBI Annotation Information: Note: MAL (Gene ID: 4118), TIRAP (Gene ID: 114609), and MKL1 (Gene ID: 57591) share the MAL symbol/alias in common. MAL is a widely used alternative name for TIR domain containing adaptor protein (TIRAP) and megakaryoblastic leukemia (translocation) 1 (MKL1). [23 May 2018]
