Enables SNAP receptor activity and protein homodimerization activity. Involved in several processes, including intracellular copper ion homeostasis; larval lymph gland hemopoiesis; and male meiosis cytokinesis. Located in cis-Golgi network. Is expressed in adult head. Human ortholog(s) of this gene implicated in congenital disorder of glycosylation type II. Orthologous to human STX5 (syntaxin 5).
FB Description
Syntaxin 5 (Syx5) encodes a type II transmembrane protein in the Q-SNARE family that forms hetero tetramers required for membrane function in the early secretory pathway (ER and Golgi). It has been involved in cytokinesis during spermatogenesis.
