Species Reactivity: Human, Mouse, Rat Source / Purification Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ser166 of human HIP1 protein. Background Huntingtin-interacting protein 1 (HIP1), a ubiquitously expressed cytosolic protein, was originally discovered by yeast two-hybrid screening for proteins that interact with the huntingtin protein. HIP1 binds the amino terminus of the huntingtin protein. This interaction is weakened by huntingtin protein mutations that cause expanded polyglutamine repeats, suggesting that HIP1 may play a role in Huntington's disease (HD) pathogenesis. HIP1, along with its human ortholog, HIP1-related protein (HIP1R) and its yeast ortholog Sla2p share a conserved domain structure; an epsin amino-terminal homology (ENTH) domain, a leucine zipper motif, and a carboxy-terminal domain homologous to TALIN (1,2). The ENTH domain of HIP1 binds clathrin and the adaptor protein AP-2, while the TALIN domain has been shown to bind actin. These interactions suggest that HIP1 plays a role in clathrin-mediated endocytosis (3-6). HIP1 has also been shown to bind receptor tyrosine kinases (RTKs), including the epidermal growth factor receptor (EGFR). Elevated expression levels of HIP1 correlate with elevated levels of EGFR and have been linked to the development and progression of various cancers (7-10).
