BIO 327 Lecture Notes - Lecture 11: Thrombin, Cadherin, Glycan
Document Summary
Control cell fate determination and function: combinatorial control of gene expression via transcription factors, signal transduction mechanisms leading to immediate and long term changes in gene expression. Multi-cellularity allows organisms to set aside some cells as reserve or self-renewing pool of cells. Replacement of skin cells from a dividing pool in the basal layer of the epidermis. Blood and circulating immune cells are replenished in a continual basis. Transfer cells | special form of parenchyma cell that works in plasma membrane transport. Facilitates rapid transport of solutes and water to plant"s vascular system. Microtubule orientation helps to determine cell shape and division plane in plants. Collagen secreted protein in mammalian and other animal cells that performs a similar function to cellulose. Triple-stranded helix that is further organized into fibrils bundles called fibers. Examples of protease mediated pathways or protein functions in cells: Correct assembly and processing of proinsulin into mature/functional insulin.
