What's a GeneRIF?

Sec16 function in ER export and autophagy is independent of its phosphorylation in Saccharomyces cerevisiae.
Title: Sec16 function in ER export and autophagy is independent of its phosphorylation in Saccharomyces cerevisiae.
the present study sheds light on both the structural and the regulatory functions of Sec16. Our data explain at least in part the mechanism for how Sec16 functions in relation to the COPII coat proteins in the ER.
Title: Insights into structural and regulatory roles of Sec16 in COPII vesicle formation at ER exit sites.
association of Sec24p with Sec16p creates a regulatory complex that retards the GTPase activity of the COPII coat to prevent premature vesicle scission
Title: Sec24p and Sec16p cooperate to regulate the GTP cycle of the COPII coat.
