SURF4 is located in the surfeit gene cluster, which is comprised of very tightly linked housekeeping genes that do not share sequence similarity. Additionally we are shipping Surfeit 4 Antibodies (44) and Surfeit 4 Proteins (4) and many more products for this protein.
Silencing Surf4 together with ERGIC-53 or silencing the p24 family member p25 induced an identical phenotype characterized by a reduced number of ERGIC clusters and fragmentation of the Golgi apparatus without effect on anterograde transport.
These findings suggest the modulatory function of Surf4 for STIM1 (show STIM1 ELISA Kits)-mediated store-operated Ca(2 (show CA2 ELISA Kits)+) entry.
This gene is located in the surfeit gene cluster, which is comprised of very tightly linked housekeeping genes that do not share sequence similarity. The encoded protein is a conserved integral membrane protein containing multiple putative transmembrane regions. In eukaryotic cells, protein transport between the endoplasmic reticulum and Golgi compartments is mediated in part by non-clathrin-coated vesicular coat proteins (COPs). The specific function of this protein has not been determined but its yeast homolog is directly required for packaging glycosylated pro-alpha-factor into COPII vesicles. This gene uses multiple polyadenylation sites, resulting in transcript length variation. The existence of alternatively spliced transcript variants has been suggested, but their validity has not been determined.
