DESCRIPTION

Also known as ATLA1_HUMAN, ATL1, GBP3, SPG3A. GTPase tethering membranes through formation of trans-homooligomers and mediating homotypic fusion of endoplasmic reticulum membranes. Functions in endoplasmic reticulum tubular network biogenesis (PubMed:27619977). May also regulate Golgi biogenesis. May regulate axonal development. Monomer as apoprotein and in the GDP-bound form. Homodimer in the GTP-bound form. Interacts (via N-terminal region) with MAP4K4 (via CNH regulatory domain). Interacts with REEP5, RTN3 and RTN4 (via the transmembrane region). Interacts with SPAST; interaction is direct. May interact with TMED2. Interacts with REEP1. Interacts with CPT1C. Interacts with ARL6IP1 (By similarity). Interacts with ZFYVE27 (PubMed:23969831).
