| Primary Identifier | IPR035456 | Type | Domain |
| Short Name | SH3BP4_SH3 |
| description | This entry represents the SH3 domain of SH3BP4 (SH3 domain-binding protein 4). SH3BP4 binds to the inactive Rag GTPase complex through its Src homology 3 (SH3) domain and acts as a negative regulator of amino acid-Rag GTPase-mTORC1 signaling []. It has been shown to act as an endocytic accessory protein that interacts with endocytic proteins including clathrin and dynamin, and regulates the internalization of the transferrin receptor (TfR) []. |
