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 and smooth muscle cell differentiation. Localizes to the 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]
