SCFD2 (Sec1 Family Domain-containing Protein 2), also known as SYTL2 or synaptotagmin-like protein 2. is a cytoplasmic protein belonging to the Sec1/Munc18 (SM) protein family. It contains a conserved N-terminal Sec1 domain and a C-terminal tandem PH-GL domain, which facilitate interactions with SNARE proteins and phospholipids. SCFD2 plays a critical role in regulating intracellular membrane trafficking, particularly in vesicle docking, fusion, and exocytosis. It functions as a molecular chaperone by binding to syntaxin-family SNAREs, modulating their assembly into functional complexes essential for cargo transport. Studies link SCFD2 to neuronal processes, including neurotransmitter release, and its dysregulation is implicated in neurodegenerative diseases (e.g., ALS) and cancers. Recombinant human SCFD2 protein (expressed in systems like E. coli or mammalian cells) is widely used to investigate its biochemical properties, interactions with SNAREs, and role in pathological mechanisms. Its structural analysis and interaction mapping also contribute to drug discovery targeting membrane trafficking disorders.
