Description
The scaffolding protein, Rack1, is a seven-WD-domain-containing protein that has been implicated in binding to integrin beta subunit cytoplasmic domains and to members of two kinase families (src and protein kinase C, PKC) that mediate integrin bidirectional signaling.Rack1 may link protein kinase C directly to integrins and participate in the regulation of integrin functions.Rack1 regulates the localization of an essential PCP protein and acts as a molecular switch to promote PCP signaling
