Polyclonal Rabbit Affinity Purified B
APS is an SH2 and PH domain-containing adaptor protein closely related to Lnk and SH2-B (1). APS was identified as a substrate for many receptor tyrosine kinases including TrkA, insulin receptor, c-Kit and PDGF receptor (2). Tyrosine phosphorylation of APS provides docking sites for downstream signalingcomponents, mediating diverse signaling pathways. APS plays quite different roles in RTK signaling. Overexpression of APS has been shown to inhibit PDGF-induced mitogenicity, which may result from APS/c-Cbl-mediated PDGF receptor degradation (3). However, APS promotes enhanced mitogenicity in response to insulin stimulation (4). The striking difference in APS-mediated signaling between the different RTKs could lie in the mode of interaction with the respective receptor.
