They have been implicated in a wide variety of biological processes including cell adhesion, differentiation, migration, signaling, neurite outgrowth and metastasis. Laminins, composed of 3 non identical chains: laminin alpha, beta and gamma (formerly A, B1, and B2, respectively), have a cruciform structure consisting of 3 short arms, each formed by a different chain, and a long arm composed of all 3 chains. Each laminin chain is a multidomain protein encoded by a distinct gene. Several isoforms of each chain have been described. Different alpha, beta and gamma chain isomers combine to give rise to different heterotrimeric laminin isoforms which are designated by Arabic numerals in the order of their discovery, i.e. alpha1beta1gamma1 heterotrimer is laminin 1. The biological functions of the different chains and trimer molecules are largely unknown, but some of the chains have been shown to differ with respect to their tissue distribution, presumably reflecting diverse functions in vivo. This gene encodes the gamma chain isoform laminin, gamma 2. The gamma 2 chain, formerly thought to be a truncated version of beta chain (B2t), is highly homologous to the gamma 1 chain; however, it lacks domain VI, and domains V, IV and III are shorter. It is expressed in several fetal tissues but differently from gamma 1, and is specifically localized to epithelial cells in skin, lung and kidney. The gamma 2 chain together with alpha 3 and beta 3 chains constitute laminin 5 (earlier known as kalinin), which is an integral part of the anchoring filaments that connect epithelial cells to the underlying basement membrane. The epithelium-specific expression of the gamma 2 chain implied its role as an epithelium attachment molecule, and mutations in this gene have been associated with junctional epidermolysis bullosa, a skin disease characterized by blisters due to disruption of the epidermal-dermal junction. Two transcript variants resulting from alternative splicing of the 3' terminal exon, and encoding different isoforms of gamma 2 chain, have been described. The two variants are differentially expressed in embryonic tissues, however, the biological significance of the two forms is not known. Transcript variants utilizing alternative polyA_signal have also been noted in literature.

Ladsin exerts cell- scattering activity toward a wide variety of cells, including epithelial, endothelial, and fibroblastic cells. {ECO:0000269|PubMed:8265624}. |Laminin B| |Laminin EGF| |laminin-2 complex| |hemidesmosome assembly| |cell-substrate junction assembly| |substrate adhesion-dependent cell spreading| |basement membrane| |extracellular matrix structural constituent| |cell cortex| |cell junction assembly| |heparin binding| |cell-substrate adhesion| |cell junction organization| |extracellular matrix organization| |collagen-containing extracellular matrix| |extracellular structure organization| |epidermis development| |positive regulation of cell migration| |positive regulation of cell motility| |positive regulation of cellular component movement| |positive regulation of locomotion| |cell morphogenesis involved in differentiation| |perinuclear region of cytoplasm| |cell morphogenesis| |cellular component morphogenesis| |regulation of cell migration| |regulation of cell motility| |positive regulation of cell population proliferation| |cell adhesion| |biological adhesion| |animal organ morphogenesis| |cell migration| |regulation of locomotion| |regulation of cellular component movement| |cell motility| |localization of cell| |locomotion| |movement of cell or subcellular component| |extracellular space| |regulation of cell population proliferation| |cell development| |tissue development| |extracellular region| |membrane| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp70|INK128 0.2μM R02 exp70]]|-1.94| |[[:results:exp2|5-Fluorouracil 20μM R00 exp2]]|-1.89| |[[:results:exp454|Bafilomycin-A1 0.009μM R08 exp454]]|-1.75| |[[:results:exp33|Rotenone 2μM R00 exp33]]|-1.71| No correlation found to any other genes in chemogenomics.
