Galactosidase, beta 1, also known as GLB1, is a protein which in humans is encoded by the GLB1 gene.^[5]^[6]

The GLB1 protein is a beta-galactosidase that cleaves the terminal beta-galactose from ganglioside substrates and other glycoconjugates.^[7] The GLB1 gene also encodes an elastin binding protein.^[8]

In corn (Zea mays), Glb1 is a gene coding for the storage protein globulin.
