Life is a slippery thing to define, but it consists of two very different skills: the ability to replicate, and the ability to create order. 1/27/11 LAMB3  The LAMB3 gene provides instructions for making one part (subunit) of a protein called laminin 332.  Laminins are a group of proteins that regulate cell growth, cell movement (motility), and the attachment of cells to one another (adhesion). They are also involved in the formation and organization of basement membranes, which are thin, sheet-like structures that separate and support cells in many tissues.  Laminin 332 has a particularly important role in the basement membrane that underlies the top layer of skin (the epidermis). This membrane gives strength and resiliency to the skin and creates an additional barrier between the body and its surrounding 1/27/11 ESPN  The ESPN gene provides instructions for making a protein called espin.  This protein is active in the inner ear, where it appears to play an essential role in normal hearing and balance.  Espin binds to actin, a protein that is important for cell movement and shape.  Espin is involved in the growth and maintenance of hairlike projections called stereocilia. (Stereocilia line the inner ear and bend in response to sound waves. This bending motion converts sound waves to nerve impulses.) 1/27/11 KIF1B Gene  Gene KIF1B, or otherwise known as kinesin family member...
