Human Gene ALG14 (uc001dra.2) Description and Page Index
  Description: Homo sapiens ALG14, UDP-N-acetylglucosaminyltransferase subunit (ALG14), mRNA.
RefSeq Summary (NM_144988): This gene is a member of the glycosyltransferase 1 family. The encoded protein and ALG13 are thought to be subunits of UDP-GlcNAc transferase, which catalyzes the first two committed steps in endoplasmic reticulum N-linked glycosylation. Mutations in this gene have been linked to congenital myasthenic syndrome (CMSWTA). Alternatively spliced transcript variants have been identified. [provided by RefSeq, Mar 2015].

-  Comments and Description Text from UniProtKB
DESCRIPTION: RecName: Full=UDP-N-acetylglucosamine transferase subunit ALG14 homolog;
FUNCTION: May be involved in protein N-glycosylation. May play a role in the second step of the dolichol-linked oligosaccharide pathway. May anchor the catalytic subunit ALG13 to the ER.
SUBUNIT: Heterodimer with ALG13 isoform 2 to form a functional enzyme (By similarity).
SUBCELLULAR LOCATION: Endoplasmic reticulum membrane; Single-pass membrane protein (Probable).
SIMILARITY: Belongs to the ALG14 family.

ModBase Predicted Comparative 3D Structure on Q96F25
The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
