Protein Information (annotations from UniProt)

Database IDHIV0001144
UniProt IDQ8IWJ2
Primary gene name(s)GCC2
Synonym gene name(s)KIAA0336, RANBP2L4
Protein nameGRIP and coiled-coil domain-containing protein 2
Protein functionGolgin which probably tethers transport vesicles to the trans-Golgi network, TGN and regulates vesicular transport between the endosomes and the Golgi. As a RAB9A effector it is involved in recycling of the mannose 6-phosphate receptor from the late endosomes to the TGN. May also play a role in transport between the recycling endosomes and the Golgi. Required for maintenance of the Golgi structure, it is involved in the biogenesis of noncentrosomal, Golgi-associated microtubules through recruitment of CLASP1 and CLASP2. {ECO:0000269|PubMed:16885419, ECO:0000269|PubMed:17488291, ECO:0000269|PubMed:17543864}.
