General description
Laminin subunit g2 (UniProt: Q13753; also known as Cell-scattering factor 140 kDa subunit, CSF 140 kDa subunit, Epiligrin subunit gamma, Kalinin subunit gamma, Kalinin/nicein/epiligrin 100 kDa subunit, Ladsin 140 kDa subunit, Laminin B2t chain, Laminin-5 subunit gamma, Large adhesive scatter factor 140 kDa subunit, Nicein subunit gamma) is encoded by the LAMC2 (also known as LAMB2T, LAMNB2) gene (Gene ID: 3918) in human. Laminin is a major basement membrane glycoprotein consisting of α, β, γ chains that are bound to each other by disulfide bonds. Over 15 different isoforms have been reported in the laminin family that are expressed in a tissue-specific manner and play different role in each tissue. γ2, a subunit of Laminin-5 is reported to be frequently over-expressed as a monomer or as the β2−γ3 heterodimer in invasive cancers and is regarded as an invasion marker. It has 8 EGF-like domains. The cell adhesion and motility activities of Laminin-5 are reported to be regulated by the proteolytic cleavage of the short arm of Laminin γ2 chain by BMP-1 or MT1-MMP. This cleavage releases a 45 kDa N-terminal proteolytic fragment (γ2pf). The short arm and γ2pf can be further cleaved by serine proteases and by matrix metalloproteinases resulting in the release of small N-terminal fragments. γ2pf-like fragments have been reported to be present in conditioned media of cultured cancer cells and in sera from human cancer subjects. Clone P2H targets the second N-terminal EGF-like repeat (NE2) of domain V of laminin 2. (Ref.: Sato, H., et al. (2014). Cancer Sci. 105(2); 168-175; Miyazaki, K., et al. (2016).
