Summaries for MKL1 Gene

Entrez Gene Summary for MKL1 Gene

  • 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]

GeneCards Summary for MKL1 Gene

MKL1 (Megakaryoblastic Leukemia (Translocation) 1) is a Protein Coding gene. Diseases associated with MKL1 include 'megakaryoblastic acute myeloid leukemia with t(1;22)(p13;q13)' and acute leukemia. Among its related pathways are RhoA signaling pathway. GO annotations related to this gene include sequence-specific DNA binding transcription factor activity and transcription regulatory region sequence-specific DNA binding. An important paralog of this gene is MKL2.

UniProtKB/Swiss-Prot for MKL1 Gene

  • Transcriptional coactivator of serum response factor (SRF) with the potential to modulate SRF target genes. Suppresses TNF-induced cell death by inhibiting activation of caspases; its transcriptional activity is indispensable for the antiapoptotic function. It may up-regulate antiapoptotic molecules, which in turn inhibit caspase activation (By similarity).

Subcellular locations from UniProtKB/Swiss-Prot for MKL1 Gene

Nucleus. Cytoplasm. Note=Binding to globular actin is required to maintain cytoplasmic localization. Nuclear localization is regulated by MICAL2, which mediates depolymerization of nuclear globular actin, promoting retention of MKL1 in the nucleus and subsequent formation of an active complex with SRF (PubMed:24440334). {ECO:0000269 PubMed:24440334}.

Disorders for MKL1 Gene


  • Note=A chromosomal aberration involving MKL1 may be a cause of acute megakaryoblastic leukemia. Translocation t(1;22)(p13;q13) with RBM15. Although both reciprocal fusion transcripts are detected in acute megakaryoblastic leukemia (AMKL, FAB-M7), the RBM15-MKL1 chimeric protein has all the putative functional domains encoded by each gene and is the candidate oncogene.
