SEC13 — SEC13 homolog, nuclear pore and COPII coat complex component
SEC13 belongs to a gene co-expression module in 2 of 28 SCUBA cell types. Each module groups genes that rise and fall together in that cell type; the genes it shares a module with are its closest co-expression partners there.

Function
Functions as a component of the nuclear pore complex (NPC) and the COPII coat. At the endoplasmic reticulum, SEC13 is involved in the biogenesis of COPII-coated vesicles. Required for the exit of adipsin (CFD/ADN), an adipocyte-secreted protein from the endoplasmic reticulum (By similarity). As a component of the GATOR2 complex, functions as an activator of the amino acid-sensing branch of the mTORC1 signaling pathway. The GATOR2 complex indirectly activates mTORC1 through the inhibition of the GATOR1 subcomplex. GATOR2 probably acts as an E3 ubiquitin-protein ligase toward GATOR1. 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. In the absence of amino acids, GATOR2 is inhibited, activating the GATOR1 complex. Within the GATOR2 complex, SEC13 and SEH1L are required to stabilize the complex.
