    Summary
    This gene encodes a member of the glycosyltransferase 1 family. The encoded protein acts as an alpha 1,3 mannosyltransferase, mannosylating Man(2)GlcNAc(2)-dolichol diphosphate and Man(1)GlcNAc(2)-dolichol diphosphate to form Man(3)GlcNAc(2)-dolichol diphosphate. Defects in this gene have been associated with congenital disorder of glycosylation type Ih (CDG-Ii). Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2008]
    Annotation information
    Note: ALG2 (Gene ID: 85365) and PDCD6 (Gene ID: 10016) share the ALG2 symbol/alias in common. ALG2 is a widely used alternative name for programmed cell death 6 (PDCD6), whose synonym is apoptosis-linked gene-2. This can be confused with the official symbol for ALG2, alpha-1,3/1,6-mannosyltransferase (ALG2). [31 May 2018]

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

      GT1_ALG2_like; This family is most closely related to the GT1 family of glycosyltransferases. ALG2, a 1,3-mannosyltransferase, in yeast catalyzes the mannosylation of Man(2)GlcNAc(2)-dolichol diphosphate and Man(1)GlcNAc(2)-dolichol diphosphate to form Man(3)GlcNAc(2) ...

      Description
      Transcript Variant: This variant (2) includes an additional exon, compared to variant 1, which results in a frameshift and early stop codon. The predicted protein is not represented because the product is significantly truncated and the transcript is a candidate for nonsense-mediated decay (NMD).
