General annotation (Comments)

Function	Alpha-L-fucosidase is responsible for hydrolyzing the alpha-1,6-linked fucose joined to the reducing-end N-acetylglucosamine of the carbohydrate moieties of glycoproteins.
Catalytic activity	An alpha-L-fucoside + H2O = L-fucose + an alcohol.
Subunit structure	Homotetramer.
Subcellular location	Lysosome.
Polymorphism	There are two common alleles of FUCA1; FUCA1*1; also known as Fu1; has Arg-281 and FUCA1*2; also known as Fu2; has Gln-281.
Involvement in disease	Defects in FUCA1 are the cause of fucosidosis (FUCA1D) [MIM:230000]. FUCA1D is an autosomal recessive lysosomal storage disease characterized by accumulation of fucose-containing glycolipids and glycoproteins in various tissues. Clinical signs include facial dysmorphism, dysostosis multiplex, moderate hepatomegaly, severe intellectual deficit, deafness, and according to age, angiokeratomas. Ref.1 Ref.15 Ref.17
Sequence similarities	Belongs to the glycosyl hydrolase 29 family.
Sequence caution	The sequence CAA25646.1 differs from that shown. Reason: Miscellaneous discrepancy. Translation of X01390 sequence produces a larger peptide than that shown in CAA25646.1.
