REPS1 is a RalBP1-associated EH-homology domain containing protein. The sequence of REPS1 has an EH domain, followed by two proline-rich segments, and a C-terminal coiled-coil domain for binding to RalBP1 (1). The EH domain of REPS1 interacts with the NPF motif of Rab11-FIP2, mediates their colocalization to endosome vesicles, and influences EGFR endocytosis (2). The two proline-rich regions of REPS1 are important for binding to the SH3 domain of GRK/GRB2 and further regulate EGFR downstream signaling. The proline-rich regions of REPS1 have also been shown to interact with the SH3 domain of intersectin1 (ITSN1) and contribute to ITSN1/SGIP1/REPS1 complex formation on clathrin-coated pits (3). Three alternatively spliced isoforms of REPS1 have been identified.

REPS1是一个含有RalBP1-associated EH同源结构域的蛋白。REPS1含有一个EH结构域,紧随其后的是2个富含脯氨酸的区域,以及一个C末端螺旋换结构域以结合RalBP1(1)。REPS1的EH结构域与Rab11-FIP2的NPF结构域结合,接到了他们共定位到核内体囊泡,影响EGFR内吞(2)。REPS1的两个富含脯氨酸的区域对于蛋白与GRK/GRB2的SH3结构域结合是非常重要的而且能够调控EGFR下游的信号通路。RESP1富含脯氨酸的区域也被认为可以和intersectin1 (ITSN1)的SH3结构域结合,引起网格蛋白小窝形成ITSN1/SGIP1/REPS1复合物(3)。REPS1发现了3中剪切异构体。

Phosphorylation of REPS1 at Ser709 was identified at Cell Signaling Technology using PTMScan® Technology, our LC-MS/MS platform for phosphorylation site discovery (4).
