Tissue specificity：Isoform 1 is preferentially expressed in striated muscle. Non-kinase form such as isoform 3 is predominantly expressed in the aorta. Isoform 3 appears to be expressed only in highly differentiated ASMC in normal vessel walls and down-regulated in dedifferentiated ASMC in vivo. In response to vascular injuries ASMC dedifferentiate and change from a quiescent and contractile phenotype to a proliferative and synthetic phenotype. This proliferation of vascular smooth muscle cells is one of the most prominent features of atherosclerosis. {ECO:0000269|PubMed:15185077, ECO:0000269|PubMed:8663449}.
Induction：Isoform 3 is quickly down-regulated in response to vascular injury, when ASMC cells change from a quiescent to a proliferative phenotype. {ECO:0000269|PubMed:8663449}.
Developmental stage：
Protein families：Protein kinase superfamily, CAMK Ser/Thr protein kinase family
