Summaries for GLB1 Gene

Entrez Gene Summary for GLB1 Gene

  • This gene encodes a member of the glycosyl hydrolase 35 family of proteins. Alternative splicing results in multiple transcript variants, at least one of which encodes a preproprotein that is proteolytically processed to generate the mature lysosomal enzyme. This enzyme catalyzes the hydrolysis of a terminal beta-linked galactose residue from ganglioside substrates and other glycoconjugates. Mutations in this gene may result in GM1-gangliosidosis and Morquio B syndrome. [provided by RefSeq, Nov 2015]

GeneCards Summary for GLB1 Gene

GLB1 (Galactosidase Beta 1) is a Protein Coding gene. Diseases associated with GLB1 include gm1-gangliosidosis, type i and gm1-gangliosidosis, type ii. Among its related pathways are Metabolism and Transport to the Golgi and subsequent modification. GO annotations related to this gene include hydrolase activity, hydrolyzing O-glycosyl compounds and galactoside binding. An important paralog of this gene is GLB1L2.

UniProtKB/Swiss-Prot for GLB1 Gene

  • Cleaves beta-linked terminal galactosyl residues from gangliosides, glycoproteins, and glycosaminoglycans.

  • Isoform 2 has no beta-galactosidase catalytic activity, but plays functional roles in the formation of extracellular elastic fibers (elastogenesis) and in the development of connective tissue. Seems to be identical to the elastin-binding protein (EBP), a major component of the non-integrin cell surface receptor expressed on fibroblasts, smooth muscle cells, chondroblasts, leukocytes, and certain cancer cell types. In elastin producing cells, associates with tropoelastin intracellularly and functions as a recycling molecular chaperone which facilitates the secretions of tropoelastin and its assembly into elastic fibers.

  • GM1-gangliosidosis 1 (GM1G1) [MIM:230500]: An autosomal recessive lysosomal storage disease marked by the accumulation of GM1 gangliosides, glycoproteins and keratan sulfate primarily in neurons of the central nervous system. GM1-gangliosidosis type 1 is characterized by onset within the first three months of life, central nervous system degeneration, coarse facial features, hepatosplenomegaly, skeletal dysmorphology reminiscent of Hurler syndrome, and rapidly progressive psychomotor deterioration. Urinary oligosaccharide levels are high. It leads to death usually between the first and second year of life. {ECO:0000269 PubMed:10338095, ECO:0000269 PubMed:10737981, ECO:0000269 PubMed:10839995, ECO:0000269 PubMed:1487238, ECO:0000269 PubMed:15365997, ECO:0000269 PubMed:15714521, ECO:0000269 PubMed:15791924, ECO:0000269 PubMed:16538002, ECO:0000269 PubMed:16941474, ECO:0000269 PubMed:17309651, ECO:0000269 PubMed:17664528, ECO:0000269 PubMed:1907800, ECO:0000269 PubMed:1909089, ECO:0000269 PubMed:1928092, ECO:0000269 PubMed:19472408, ECO:0000269 PubMed:25936995, ECO:0000269 PubMed:8213816, ECO:0000269 Ref.24, ECO:0000269 Ref.27}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • GM1-gangliosidosis 2 (GM1G2) [MIM:230600]: A gangliosidosis characterized by onset between ages 1 and 5. The main symptom is locomotor ataxia, ultimately leading to a state of decerebration with epileptic seizures. Patients do not display the skeletal changes associated with the infantile form, but they nonetheless excrete elevated amounts of beta-linked galactose-terminal oligosaccharides. Inheritance is autosomal recessive. {ECO:0000269 PubMed:10737981, ECO:0000269 PubMed:12644936, ECO:0000269 PubMed:15714521, ECO:0000269 PubMed:16941474, ECO:0000269 PubMed:17309651, ECO:0000269 PubMed:1907800, ECO:0000269 PubMed:1909089, ECO:0000269 PubMed:19472408, ECO:0000269 PubMed:25936995, ECO:0000269 PubMed:8213816}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • GM1-gangliosidosis 3 (GM1G3) [MIM:230650]: A gangliosidosis with a variable phenotype. Patients show mild skeletal abnormalities, dysarthria, gait disturbance, dystonia and visual impairment. Visceromegaly is absent. Intellectual deficit can initially be mild or absent but progresses over time. Inheritance is autosomal recessive. {ECO:0000269 PubMed:11511921, ECO:0000269 PubMed:15986423, ECO:0000269 PubMed:16941474, ECO:0000269 PubMed:17309651, ECO:0000269 PubMed:17664528, ECO:0000269 PubMed:1907800, ECO:0000269 PubMed:1909089, ECO:0000269 PubMed:19472408, ECO:0000269 PubMed:25936995, ECO:0000269 PubMed:8198123, ECO:0000269 Ref.24, ECO:0000269 Ref.26}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Mucopolysaccharidosis 4B (MPS4B) [MIM:253010]: A form of mucopolysaccharidosis type 4, an autosomal recessive lysosomal storage disease characterized by intracellular accumulation of keratan sulfate and chondroitin-6-sulfate. Key clinical features include short stature, skeletal dysplasia, dental anomalies, and corneal clouding. Intelligence is normal and there is no direct central nervous system involvement, although the skeletal changes may result in neurologic complications. There is variable severity, but patients with the severe phenotype usually do not survive past the second or third decade of life. {ECO:0000269 PubMed:11511921, ECO:0000269 PubMed:12393180, ECO:0000269 PubMed:16538002, ECO:0000269 PubMed:16941474, ECO:0000269 PubMed:17664528, ECO:0000269 PubMed:1928092, ECO:0000269 PubMed:19472408, ECO:0000269 PubMed:7586649}.
