Genes affected

B3GNTL1 (HGNC:21727): (UDP-GlcNAc:betaGal beta-1,3-N-acetylglucosaminyltransferase like 1) Predicted to enable glycosyltransferase activity. [provided by Alliance of Genome Resources, Apr 2022]

B3GNTL1 links:

TBCD (HGNC:11581): (tubulin folding cofactor D) Cofactor D is one of four proteins (cofactors A, D, E, and C) involved in the pathway leading to correctly folded beta-tubulin from folding intermediates. Cofactors A and D are believed to play a role in capturing and stabilizing beta-tubulin intermediates in a quasi-native confirmation. Cofactor E binds to the cofactor D/beta-tubulin complex; interaction with cofactor C then causes the release of beta-tubulin polypeptides that are committed to the native state.
