== Function == | |||
[[http://www.uniprot.org/uniprot/SGIP1_HUMAN SGIP1_HUMAN]] May function in clathrin-mediated endocytosis. Has both a membrane binding/tubulating activity and the ability to recruit proteins essential to the formation of functional clathrin-coated pits. Has a preference for membranes enriched in phosphatidylserine and phosphoinositides and is required for the endocytosis of the transferrin receptor. May also bind tubulin. May play a role in the regulation of energy homeostasis (By similarity). | |||

== Publication Abstract from PubMed == | |||
FCHo1, FCHo2, and SGIP1 are key regulators of clathrin-mediated endocytosis. Their mu homology domains (muHDs) interact with the C-terminal region of an endocytic scaffold protein, Eps15, containing fifteen Asp-Pro-Phe (DPF) motifs. Here, we show that the high-affinity muHD-binding site in Eps15 is a region encompassing six consecutive DPF motifs, while the minimal muHD-binding unit is two consecutive DPF motifs. We present the crystal structures of the SGIP1 muHD in complex with peptides containing two DPF motifs. The peptides bind to a novel ligand-binding site of the muHD, which is distinct from those of other distantly related muHD-containing proteins. The two DPF motifs, which adopt three-dimensional structures stabilized by sequence-specific intramotif and intermotif interactions, are extensively recognized by the muHD and are both required for binding. Thus, consecutive and singly scattered DPF motifs play distinct roles in muHD binding. | |||
