immunoblotting: 1-2 μg/mL using extracts of SH-SY5Y cells and of mouse brain (S1 fraction). immunohistochemistry: 10-20 μg/mL using formalin-fixed, paraffin-embedded rat brain. indirect immunofluorescence: 2-4 μg/mL using NRK cells.
There are three known mammalian epsin variants including epsin 1, 2 and 3. Epsin1 protein contains an epsin N-terminal homology (ENTH) region, a single clathrin-binding LVDLD motif and two or three tandem ubiquitin-interacting motifs (UIMs). The central region of epsin contains a clathrin interaction motif as well as repeats of a DPW motif, which binds to adaptor protein (AP)-2.

생화학적/생리학적 작용
Epsin1 (also known as EPN1) is an endocytic adaptor protein that plays a central role in the clathrin-mediated internalization and degradation of ubiquinated proteins. Epsin1 recruits ubiquitinated epidermal growth factor receptor (EGFR) into clathrin-coated pits. Epsin1 is required in mitotic membrane and spindle organization. The epsin family of endocytic adaptors is found to be upregulated in cancer and epsin1 overexpression promotes cancer cell invasion.

Clathrin-mediated endocytosis sorts for degradation of more than 50 different growth factor receptors capable of relaying growth and differentiation signals by means of their cytoplasm-facing, intrinsic tyrosine kinase activity. The kinetics and alternative routings of receptor endocytosis critically regulate growth
