Background: MS4A3

MS4A3, also known as HTm4, is an membrane protein that is a member of the MS4A family of four-transmembrane proteins that also includes CD20 and Fc epsilon RI beta.  MS4A3 is a cell cycle regulator expressed in the perinuclear area of human basophils, eosinophils, early embryonic neural progenitors, splenic red pulp macrophages, monocytes and bile duct plus pancreatic duct epithelium. The C-terminal region of MS4A3 interacts with cdc-associated phosphatase (KAP), enhancing its activity on cyclin-dependent kinase 2 (cdk2) and facilitating G(0)/G(1) arrest. The combined non-membrane segments of the 214 amino acid (aa), 22-25 kDa human MS4A3 show 53% and 52% aa identity with corresponding regions of mouse and rat MS4A3, respectively.
