Human Gene AGL (ENST00000294724.8) from GENCODE V44
  Description: Homo sapiens amylo-alpha-1, 6-glucosidase, 4-alpha-glucanotransferase (AGL), transcript variant 4, mRNA. (from RefSeq NM_000028)
RefSeq Summary (NM_000028): This gene encodes the glycogen debrancher enzyme which is involved in glycogen degradation. This enzyme has two independent catalytic activities which occur at different sites on the protein: a 4-alpha-glucotransferase activity and a amylo-1,6-glucosidase activity. Mutations in this gene are associated with glycogen storage disease although a wide range of enzymatic and clinical variability occurs which may be due to tissue-specific alternative splicing. Alternatively spliced transcripts encoding different isoforms have been described. [provided by RefSeq, Jul 2008].

  ID: GDE_HUMAN
DESCRIPTION: RecName: Full=Glycogen debranching enzyme; AltName: Full=Glycogen debrancher; Includes: RecName: Full=4-alpha-glucanotransferase; EC=2.4.1.25; AltName: Full=Oligo-1,4-1,4-glucantransferase; Includes: RecName: Full=Amylo-alpha-1,6-glucosidase; Short=Amylo-1,6-glucosidase; EC=3.2.1.33; AltName: Full=Dextrin 6-alpha-D-glucosidase;
FUNCTION: Multifunctional enzyme acting as 1,4-alpha-D-glucan:1,4- alpha-D-glucan 4-alpha-D-glycosyltransferase and amylo-1,6- glucosidase in glycogen degradation.
CATALYTIC ACTIVITY: Transfers a segment of a (1->4)-alpha-D-glucan to a new position in an acceptor, which may be glucose or a (1->4)-alpha-D-glucan.
CATALYTIC ACTIVITY: Hydrolysis of (1->6)-alpha-D-glucosidic branch linkages in glycogen phosphorylase limit dextrin.
SUBUNIT: Monomer. Interacts with NHLRC1/malin.
SUBCELLULAR LOCATION: Cytoplasm. Note=Under glycogenolytic conditions localizes to the nucleus.
TISSUE SPECIFICITY: Liver, kidney and lymphoblastoid cells express predominantly isoform 1; whereas muscle and heart express not only isoform 1, but also muscle-specific isoform mRNAs (isoforms 2, 3 and 4). Isoforms 5 and 6 are present in both liver and muscle.
PTM: The N-terminus is blocked.
PTM: Ubiquitinated.
DISEASE: Defects in AGL are the cause of glycogen storage disease type 3 (GSD3) [MIM:232400]; also known as Forbes disease. GSD3 is a metabolic disorder associated with an accumulation of abnormal glycogen with short outer chains. Three GSD3 types are recognized: GSD type 3A patients lack glycogen debrancher enzyme activity in both liver and muscle, while GSD type 3B patients are enzyme- deficient in liver only. In rare cases, selective loss of only 1 of the 2 debranching activities, glucosidase or transferase, results in GSD type 3C or type 3D, respectively. GSD3 is clinically characterized by hepatomegaly, hypoglycemia, short stature, and variable myopathy.
SIMILARITY: Belongs to the glycogen debranching enzyme family.

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.
