Detects myozap (myocardium zonula adherens protein), a major 54 kD polypeptide present in myocardial junctions (composite junctions in the intercalated disks), also localized in adherens type junctions of the entire cardiovascular system and in endothelia of the blood and lymph vascular systems.Reactivity on cultured cell lines: HL-1, HUVEC.Positive control: myocard.
MYOZAP, also known as GRINL1A, is a 54 kDa highly conserved cardiac protein. It is strongly expressed in the heart and lung and is a novel component of intercalated disc. MYOZAP interacts with myosin phosphatase-RhoA interacting protein (MRIP) and acts as an activator of Rho-dependent SRF signaling. Knockdown study in zebrafish results in cardiomyopathy with severe dysfunction. The MYOZAP gene is part of a complex transcript unit that includes the gene for glutamate receptor, ionotropic, N-methyl D-aspartate-like 1A (GRINL1A). Transcription of this gene occurs at an upstream promoter, with two different groups of alternatively spliced variants: Gup for GRINL1A upstream transcripts and Gcom for GRINL1A combined transcripts.
