Regional differences in the polypeptide composition of pig lens intracellular matrix and plasma membrane
Abstract:
Analysis of pig lens urea-soluble fractions (USF) by gel filtration and SDS-PAGE revealed that the cortical USF is characterized by a high content of noncrystallin bands of 42, 44, 52, 55, 100 and 200 kD. These bands are markedly decreased in the nuclear USF though the 44-kD band to a lesser extent. These results suggested that pig lens nucleus contains much less cytoskeletal proteins than the cortex. Analysis of pig lens membrane showed that MP26 and MP17 are the major intrinsic membrane proteins and the relative amount of alpha A and beta B1b chains attached to the membrane are more abundant in the nucleus than in the cortex.

The Extracellular Matrix
In order to maintain tissue organization, many animal cells are surrounded by structural molecules that make up the extracellular matrix (ECM). Together, the molecules in the ECM maintain the structural integrity of tissue as well as the remarkable specific properties of certain tissues.
Composition of the Extracellular Matrix
The extracellular matrix (ECM) is commonly composed of ground substance, a gel-like fluid, fibrous components, and many structurally and functionally diverse...
