In our efforts to identify cellular tyrosine kinases that phosphorylate SCAMPs, we are quite intrigued by the observation that among a number of kinases, only the EGFR exhibits activity toward SCAMPs. EGF catalyzes the progressive phosphorylation of the SCAMPs up to 1 h poststimulation and may enhance colocalization of the EGFR and SCAMP3 within the cell interior. EGF also induces SCAMP-EGFR association, as detected by coimmunoprecipitation, and phosphorylation of SCAMP3 is stimulated by the EGFR in vitro. These results suggest that phosphorylation of SCAMPs, either directly or indirectly, may be functionally linked to the internalization/down-regulation of the EGFR. we have observed that there are two tyrosines conserved in SCAMP1 and SCAMP3, which are not found in SCAMP2. Of these two tyrosines (Tyr37 and Tyr73 in SCAMP1; Tyr 41 and Tyr83 in SCAMP3), we consider Tyr37/41 to be a more likely site for tyrosine phosphorylation |
