    Summary
    The protein encoded by this gene interacts with the transcription factor myocardin, a key regulator of smooth muscle cell differentiation. The encoded protein is predominantly nuclear and may help transduce signals from the cytoskeleton to the nucleus. This gene is involved in a specific translocation event that creates a fusion of this gene and the RNA-binding motif protein-15 gene. This translocation has been associated with acute megakaryocytic leukemia. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2013]
    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]

    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.
