Exocyst complex component Sec3, C-terminal (IPR019160)

Short name: Sec3_C

Overlapping homologous superfamilies


Domain relationships



This entry represents the C-terminal domain of Sec3 (also known as Exoc1), a component of the exocyst complex (composed of Exoc1, Exoc2, Exoc3, Exoc4, Exoc5, Exoc6, Exoc7 and Exoc8).

Sec3 binds to the C-terminal cytoplasmic domain of GLYT1 (glycine transporter protein 1). Sec3 is the exocyst component that is closest to the plasma membrane docking site and it serves as a spatial landmark in the plasma membrane for incoming secretory vesicles. Sec3 is recruited to the sites of polarised membrane growth through its interaction with Rho1p, a small GTP-binding protein [PMID: 16181645].
