This gene encodes a glycosyltransferase that catalyzes the addition of a single N-acetylglucosamine in O-glycosidic linkage to serine or threonine residues. Since both phosphorylation and glycosylation compete for similar serine or threonine residues, the two processes may compete for sites, or they may alter the substrate specificity of nearby sites by steric or electrostatic effects. The protein contains multiple tetratricopeptide repeats that are required for optimal recognition of substrates. Alternatively spliced transcript variants encoding distinct isoforms have been found for this gene. [provided by RefSeq, Oct 2009]

Interaction
Monomer; may exist in different oligomerization states in cells (PubMed:21240259). Homotrimer, oligomerizes via TPR repeats 6 and 7. Trimerization is not necessary for activity in vitro, however it increases affinity for UDP-GlcNAc (By similarity). Component of a THAP1/THAP3-HCFC1-OGT complex (PubMed:20200153). Component of the NSL complex at least composed of MOF/KAT8, KANSL1, KANSL2, KANSL3, MCRS1, PHF20, OGT1/OGT, WDR5 and HCFC1 (PubMed:20018852). Interacts directly with HCFC1; the interaction O-glycosylates HCFC1, regulates its proteolytic processing and transcriptional activity and, in turn, stabilizes OGT in the nucleus (PubMed:12670868, PubMed:20200153, PubMed:21285374, PubMed:23353889). Interacts (via TPRs 1-6) with SIN3A; the interaction mediates transcriptional repression in parallel with histone deacetylase (PubMed:12150998). Interacts (via TPR 5-6) with TET1, TET2 and TET3 (PubMed:23353889, PubMed:23222540). Interacts (via TPR repeats 6 and 7) with ATXN10 (By similarity). Interacts with histone H2B (PubMed:22121020). Interacts with ARNTL/BMAL1. Found in a complex composed of at least SINHCAF, SIN3A, HDAC1, SAP30, RBBP4, OGT and TET1. Interacts with SINHCAF (By similarity). Component of a complex composed of KMT2E/MLL5 (isoform 3), OGT (isoform 1) and USP7; the complex stabilizes KMT2E/MLL5, preventing KMT2E/MLL5 ubiquitination and proteosomal-mediated degradation (PubMed:26678539). Isoform 1 interacts (via TRP repeats) with isoform 3 KMT2E/MLL5 (via N-terminus) (PubMed:26678539, PubMed:23629655). Isoform 1 interacts with USP7 (PubMed:26678539). Interacts with TRAK1; this interaction is not required for glycosylation of TRAK1 by this protein. Found in a complex with KIF5B, RHOT1, RHOT2 and TRAK1 (PubMed:24995978). Interacts (via TPR repeats domain) with HOXA1; the interaction takes place mainly in the nucleus (By similarity). Interacts with NSD2 (By similarity). (Microbial infection) Interacts with human T-cell leukemia virus 1/HTLV-1 protein Tax; this interaction increases Tax interacting partner CREB1 O-GlcNAcylation.
