这个基因的产物属于一个小的转接器蛋白家族，已知它与许多受体酪氨酸激酶和信号分子相互作用。该基因编码一种与表皮生长因子受体（EGFR）和肾上腺素受体相互作用的生长因子受体结合蛋白该蛋白通过与粘着斑激酶（FAK）结合在整合素信号通路和细胞迁移中发挥作用已经发现了编码两种不同亚型的转录变体[由RefSeq提供，2011年6月]
The product of this gene belongs to a small family of adapter proteins that are known to interact with a number of receptor tyrosine kinases and signaling molecules. This gene encodes a growth factor receptor-binding protein that interacts with epidermal growth factor receptor (EGFR) and ephrin receptors. The protein plays a role in the integrin signaling pathway and cell migration by binding with focal adhesion kinase (FAK). Several transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Jun 2011]
