Laminins are heterotrimeric molecules composed of an a , a b , and a g chain; they have broad functional roles in development and in stabilizing epithelial structures. Here, we identified a novel laminin, composed of known a and b chains but containing a novel g chain, g 3. We have cloned gene encoding this chain, LAMC3, which maps to chromosome 9 at q31-34. Protein and cDNA analyses demonstrat...
