The function of ENSG00000170266 (GLB1, galactosidase beta 1) is as follows. [Isoform 1]: Cleaves beta-linked terminal galactosyl residues from gangliosides, glycoproteins, and glycosaminoglycans. {ECO:0000269|PubMed:15714521, ECO:0000269|PubMed:19472408, ECO:0000269|PubMed:2511208, ECO:0000269|PubMed:25936995, ECO:0000269|PubMed:8200356}. [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. {ECO:0000269|PubMed:10841810, ECO:0000269|PubMed:8922281}.
