Sec3A
Sec3A is a protein encoded by the SEC3A gene in humans. This gene is part of the Sec machinery, a complex system involved in protein secretion and transport within cells. Sec3A plays a role in the exocyst complex, a group of proteins that mediates the tethering of transport vesicles to the plasma membrane during exocytosis. The exocyst complex is crucial for a variety of cellular processes, including cell growth, migration, and the secretion of hormones and neurotransmitters. Specifically, Sec3A is believed to contribute to the structural integrity and function of the exocyst by facilitating its interaction with other components and with the target membrane. Dysregulation of Sec3A has been implicated in certain cellular abnormalities, although its precise contribution to disease is an area of ongoing research. Understanding the function of Sec3A and its role within the exocyst complex provides insights into fundamental cellular trafficking pathways.
