Recombinant Human Golgi reassembly-stacking protein 2 (GORASP2)

Uniprot Id

Q9H8Y8

Target Species

Human

Target Name

GORASP2

Target Full Name

Golgi reassembly-stacking protein 2

Target Function

Plays a role in the assembly and membrane stacking of the Golgi cisternae, and in the process by which Golgi stacks reform after breakdown during mitosis and meiosis. May regulate the intracellular transport and presentation of a defined set of transmembrane proteins, such as transmembrane TGFA. Required for normal acrosome formation during spermiogenesis and normal male fertility, probably by promoting colocalization of JAM2 and JAM3 at contact sites between germ cells and Sertoli cells. Mediates ER stress-induced unconventional (ER/Golgi-independent) trafficking of core-glycosylated CFTR to cell membrane.

Target Subcellular Location

Golgi apparatus membrane; Lipid-anchor. Endoplasmic reticulum membrane. Golgi apparatus.

Target Background

This gene encodes a member of the Golgi reassembly stacking protein family. These proteins may play a role in the stacking of Golgi cisternae and Golgi ribbon formation, as well as Golgi fragmentation during apoptosis or mitosis. The encoded protein also plays a role in the intracellular transport of transforming growth factor alpha and may function as a molecular chaperone. A pseudogene of this gene is located on the short arm of chromosome 2. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.
