The Role Of Domain I In Laminin Chain Assembly, George D. Kamphaus

Theses, Dissertations and Capstones

Laminin, a major component of basement membrane, is a trimeric glycoprotein comprised of three chains - α, β and γ (Burgeson et al., 1994). An order for trimer assembly has been deduced: first, the β and γ chains bind to form a dimer and subsequently α is added to complete the trimer (I. Hunter et al., 1990 & 1992; Utani et al., 1994 & 1995). The C-terminal portions, found within the protein structural domain I of the p and y chains, are implicated in dimer and trimer formation by biochemical studies performed extracellularly (Utani, et al., 1994 & 1995; Nomizu …
