IGBP1
Immunoglobulin-binding protein 1 is a protein that in humans is encoded by the IGBP1 gene.[1][2]
Function
The proliferation and differentiation of B cells is dependent upon a B-cell antigen receptor (BCR) complex. Binding of antigens to specific B-cell receptors results in a tyrosine phosphorylation reaction through the BCR complex and leads to multiple signal transduction pathways.[2]
Interactions
IGBP1 has been shown to interact with PPP4C,[3][4][5] PPP6C[4][5] and PPP2CA.[4][5][6][7]
