domain:The SH3 domain mediates localization to the clathrin-coated pits and vesicles. The SH3 domain mediates interaction with DNM2 and the cytoplasmic part of TFRC with a lower affinity.,function:Functions in transferrin receptor internalization at the plasma membrane through a cargo-specific control of clathrin-mediated endocytosis.,miscellaneous:Overexpression or depletion of SH3BP4 result in a specific decrease of the transferrin receptor endocytosis that can be rescued by DNM2 overexpression.,PTM:Phosphorylated upon EGF stimulation. Phosphorylation prevents interaction with DNM2.,similarity:Contains 1 SH3 domain.,subcellular location:Specifically associated with transferrin receptor-containing clathrin-coated pits and clathrin-coated vesicles. May also localize to the nucleus.,subunit:Homodimer or homooligomer. Interacts with DNM2, EPS15, clathrin, the adapter protein complex 2/AP-2 and TFRC.,tissue specificity:Expressed in all tissues tested with higher expression in pancreas. Expressed by retinal pigment epithelial cells (at protein level).,
