Gene Summary
Polypeptide N-acetylgalactosaminyltransferase 35A (Pgant35A) encodes a member of the UDP- GalNAc:polypeptide N-acetylgalactosaminyltransferase family. It catalyzes the transfer of a GalNAc sugar onto the hydroxyl groups of serine and threonine in secreted or membrane-bound proteins. The product of Pgant35A is an essential protein involved in epithelial tube polarity. [Date last reviewed: 2019-03-14] (FlyBase Gene Snapshot)

Gene Group (FlyBase)
POLYPEPTIDE N-ACETYLGALACTOSAMINYLTRANSFERASES -
Polypeptide N-acetylgalactosaminyltransferase catalyze the transfer of N-Acetylgalactosamine (GalNAc) from UDP-GalNAc to serine and threonine acceptor sites and initiate mucin-type O-glycosylation. (Adapted from FBrf0151358 and FBrf0190815).
Protein Function (UniProtKB)
Polypeptide N-acetylgalactosaminyltransferases catalyze the transfer of an N-acetyl-D-galactosamine residue to a serine or threonine residue on the protein receptor (PubMed:11925450, PubMed:12829714). Displays the same enzyme activity toward MUC1, MUC4, and EA2 (PubMed:11925450, PubMed:12829714). Not involved in glycosylation of erythropoietin (EPO) (PubMed:11925450). It can both act as a peptide transferase that transfers GalNAc onto unmodified peptide substrates, and as a glycopeptide transferase that requires the prior addition of a GalNAc on a peptide before adding additional GalNAc moieties (PubMed:11925450, PubMed:12829714). Protein modification by this enzyme might be important for cytokinesis and tube formation during embryogenesis (PubMed:16251381, PubMed:20807760). Together with Pgant3, regulates integrin levels and activity-dependent integrin signaling at the synapse in neurons and muscles (PubMed:25253852).

Model Confidence:
  • Very high (pLDDT > 90)
  • Confident (90 > pLDDT > 70)
  • Low (70 > pLDDT > 50)
  • Very low (pLDDT < 50)

AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.

Domain

There are two conserved domains in the glycosyltransferase region: the N-terminal domain (domain A, also called GT1 motif), which is probably involved in manganese coordination and substrate binding and the C-terminal domain (domain B, also called Gal/GalNAc-T motif), which is probably involved in catalytic reaction and UDP-Gal binding.

The ricin B-type lectin domain binds to GalNAc and contributes to the glycopeptide specificity.

Testis-specificity index

The testis specificity index was calculated from modENCODE tissue expression data by Vedelek et al., 2018 to indicate the degree of testis enrichment compared to other tissues. Scores range from -2.52 (underrepresented) to 5.2 (very high testis bias).

Additional Descriptive Data

Pgant35A transcripts are detected in males and females on northern blots. High levels are expressed in the ovary. Lower levels are observed in the testis and in the carcasses. Analysis of unfertilized eggs and early embryos reveals a strong maternal contribution. In situ hybridization during oogenesis reveals expression in germ cells and in follicle epithelia throughout oogenesis.

Pgant35A transcripts are detected in all stages from embryo to adult as tested by pcr and northern blot.

            The Pgant35A gene may have been derived from the CG10000 gene by retroposition.

            FlyBase curator comment: "l(2)35Aa" (FBgn0001970, Pgant35A, CG7480) is also referred to in FBrf0151358 as "dGalNAc-T1", but "l(2)35Aa" is not the same gene as the gene with the valid symbol "GalNAc-T1" in FlyBase, which is FBgn0034025, CG8182 described in FBrf0130686 (accession number AF218236).
