Phosphorylation of Caveolin-1 in Bovine Rod Outer Segments in vitro by an Endogenous Tyrosine Kinase
Caveolin-1 (Cav-1), the principal protein component of caveolar membrane domains (Glenney, Jr. and Soppet, 1992; Kurzchalia et al., 1992; Rothberg et al., 1992), was originally identified as a major tyrosine phosphoprotein in Rous sarcoma virus (v-Src) transformed cells (Glenney, Jr. and Zokas, 1989). Although Cav-1 can be phosphorylated on several tyrosine residues (Nomura and Fujimoto, 1999; Schlegel et al., 2001), the most well-characterized phosphorylation site on Cav-1 is tyrosine-14, a site specifically recognized by monoclonal antibodies developed to detect this phosphorylated residue (Lee et al., 2000; Nomura and Fujimoto, 1999).
