MARCKS
Myristoylated alanine-rich C-kinase substrate is a protein that in humans is encoded by the ''MARCKS'' gene.〔(【引用サイトリンク】 url = http://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=4082 )〕 It plays important roles in cell shape, cell motility, secretion, transmembrane transport, and regulation of the cell cycle. Recently, MARCKS has been implicated in the exocytosis of a number of vesicles and granules such as mucin and chromaffin. They are acidic proteins with high proportions of alanine, glycine, proline, and glutamic acid. They are membrane-bound through a lipid anchor at the N-terminus, and a polybasic domain in the middle. They are regulated by Ca2+/calmodulin and protein kinase C. In their unphosphorylated form, they bind to actin filaments, causing them to crosslink, and sequester acidic membrane phospholipids such as PIP2.
==Interactions== MARCKS has been shown to interact with TOB1 and with NMT2.
