Rabbit Anti-Glucosidase 2 subunit beta/FITC Conjugated antibody
background:
Trimming of glucoses from N-linked core glycans on newly synthesized glycoproteins occurs sequentially through the action of Glucosidases I and II in the endoplasmic reticulum (ER). Glucosidase II is an ER-localized enzyme that contains a and b subunits (Glucosidase IIa and Glucosidase IIb) which form a defined heterodimeric complex. Glucosidase IIa is the catalyitc core of the enzyme and can function independently of the b subunit. The sequence of Glucosidase IIb encodes protein rich in glutamic and aspartic acid with a putative ER retention signal (HDEL) at the SLCterminus. The phosphorylated form of Glucosidase IIb is localized in the plasma membrane and is highly expressed in FGF-stimulated fibroblasts and epidermal carcinoma cells. Glucosidase IIb was first purified from a human carcinoma cell line as a potential substrate for protein kinase C. Through the HDEL signal at the SLCterminus, Glucosidase IIb retains the complete complex in the ER.
Function:
Regulatory subunit of glucosidase II.
Subunit:
Heterodimer of a catalytic alpha subunit (GANAB) and abeta subunit (PRKCSH). Binds glycosylated PTPRC (By similarity).
Subcellular Location:
Endoplasmic reticulum.
DISEASE:
Defects in PRKCSH are a cause of polycystic liver disease (PCLD) [MIM:174050]. PCLD is an autosomal dominant disorder and is characterized by the presence of multiple liver cysts of biliary epithelial origin. PCLD is a distinct clinical and genetic entity that can occur independently from autosomal dominant polycystic kidney disease (ADPKD) [MIM:173900], which in a considerable but uncertain proportion of cases is associated with hepatic cysts.
Similarity:
Contains 2 EF-hand domains.
Contains 1 PRKCSH domain.
