UniprotKB/SwissProt ID: Q96EE3 (Q96EE3)
Gene Name:
SEH1L
Organism: Homo sapiens (Human)
Function: Component of the Nup107-160 subcomplex of the nuclear pore complex (NPC). The Nup107-160 subcomplex is required for the assembly of a functional NPC (PubMed:15146057, PubMed:17363900). The Nup107-160 subcomplex is also required for normal kinetochore microtubule attachment, mitotic progression and chromosome segregation. This subunit plays a role in recruitment of the Nup107-160 subcomplex to the kinetochore (PubMed:15146057, PubMed:17363900) As a component of the GATOR2 complex, functions as an activator of the amino acid-sensing branch of the mTORC1 signaling pathway (PubMed:23723238, PubMed:25457612, PubMed:27487210, PubMed:35831510, PubMed:36528027). The GATOR2 complex indirectly activates mTORC1 through the inhibition of the GATOR1 subcomplex (PubMed:23723238, PubMed:27487210, PubMed:35831510, PubMed:36528027). GATOR2 probably acts as an E3 ubiquitin-protein ligase toward GATOR1 (PubMed:36528027). In the presence of abundant amino acids, the GATOR2 complex mediates ubiquitination of the NPRL2 core component of the GATOR1 complex, leading to GATOR1 inactivation (PubMed:36528027). In the absence of amino acids, GATOR2 is inhibited, activating the GATOR1 complex (PubMed:25457612, PubMed:26972053, PubMed:27487210). Within the GATOR2 complex, SEC13 and SEH1L are required to stabilize the complex (PubMed:35831510)
