Kindlins are a novel family of cytoskeleton proteins that plays an important role in the activation of heterodimeric integrin transmembrane receptors. These receptors play a vital role in cell adhesion, cell migration and other cellular processes. The Kindlin protein family consists of three homologous proteins, Kindlin 1, 2 and 3 with differential tissue distribution and varying expression levels in human. Mutations of Kindlin 1 protein are clinically linked to Kindler Syndrome. Kindlin 2 knockdown studies have shown embryonic lethality in mouse, but no diseases have been clinically testified. Kindlin 3 mutations are associated with bleeding disorders, e.g. LADIII. Talin is …
Discovery And Identification Of New Dna Photoproducts And Investigation Of The Redox Mechanism Of Human Apurinic/Apyrimidinic Endonuclease 1 (Hape1) Protein, Dian Su
All Theses and Dissertations (ETDs)
Exposure of cells to ultraviolet light results in the formation of DNA photoproducts, many of which have been linked to skin cancer. The majority of these photoproducts arise from a photoreaction between two pyrimidines. Irradiation of double stranded B form DNA under physiological conditions mainly produces adjacent dimers. Nonadjacent photodimers of both intrastrand and interstrand types are much rarer. Intrastrand-type nonadjacent dimers form when one or more nucleotides between two pyrimidines become extrahelical owing to the formation of single strand DNA or a slipped structure. This allows the two pyrimidines to photodimerize in a colinear arrangement, as if the intervening …
