HGH1 homolog is a conserved protein that plays a role in the cellular machinery responsible for protein translocation and secretion processes. It is a homolog of the yeast HGH1 gene product, which is known to function as a guanine nucleotide exchange factor (GEF) for the ARF family of small GTPases. These GTPases are crucial in the regulation of vesicle budding and trafficking within the cell, particularly in the early secretory pathway.

In yeast, HGH1 is implicated in endoplasmic reticulum to Golgi transport, where it facilitates the exchange of GDP for GTP on ARF proteins, activating them to initiate vesicle formation. The human homolog of HGH1 retains similar functional roles, contributing to the efficiency and regulation of protein transport from the endoplasmic reticulum towards the Golgi apparatus. This step is vital for the proper modification, sorting, and delivery of proteins to their destined locations within or outside the cell.The importance of HGH1 homolog in vesicular transport means that it has a broad impact on numerous cellular processes, including the secretion of hormones, immune responses, and the plasma membrane composition. Dysregulation or dysfunction of this protein could potentially lead to a variety of cellular pathologies, given the essential nature of protein trafficking in cellular homeostasis.
