Rabbit anti-Human POFUT2 Polyclonal Antibody

Uniprot Id

Q9Y2G5

Target Species

Human

Target Name

POFUT2

Target Full Name

GDP-fucose protein O-fucosyltransferase 2

Target Function

Catalyzes the reaction that attaches fucose through an O-glycosidic linkage to a conserved serine or threonine residue in the consensus sequence C1-X(2,3)-S/T-C2-X(2)-G of thrombospondin type 1 repeats where C1 and C2 are the first and second cysteines, respectively. O-fucosylates members of several protein families including the ADAMTS family, the thrombosporin (TSP) and spondin families. The O-fucosylation of TSRs is also required for restricting epithelial to mesenchymal transition (EMT), maintaining the correct patterning of mesoderm and localization of the definite endoderm. Required for the proper secretion of ADAMTS family members such as ADAMSL1 and ADAMST13.

Target Subcellular Location

Endoplasmic reticulum. Golgi apparatus. Note=Mainly located in the endoplasmic reticulum.

Target Protein Families

Glycosyltransferase 68 family

Target Tissue Specificity

Isoform A is expressed in fetal liver and peripheral blood lymphocytes. Isoform B is expressed in spleen, lung, testis, bone marrow, thymus, pancreas, prostate, fetal brain, fetal liver and fetal kidney. Isoform C is expressed in brain, heart, spleen, liv

Target Synonyms

FUT13; C21orf80; POFUT2

Target Background

Fucose is typically found as a terminal modification of branched chain glycoconjugates, but it also exists in direct O-linkage to serine or threonine residues within cystine knot motifs in epidermal growth factor (EGF; MIM 131530)-like repeats or thrombospondin (THBS; see MIM 188060) type-1 repeats. POFUT2 is an O-fucosyltransferase that use THBS type-1 repeats as substrates (Luo et al., 2006 [PubMed 16464857]).
