l
The protein encoded by this gene interacts with the transcription factor serum response factor,[5] a key regulator of smooth muscle cell differentiation. It is closely related to MKL2 and myocardin.[6] The encoded protein can shuttle between the cytoplasm and the nucleus, and may help this way transduce signals from the cytoskeleton to the nucleus.[7]
Clinical significance
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.[4]
