BIO341H5 Lecture Notes - Lecture 18: Alpha Cell, Meiosis, Gene Conversion
Document Summary
Haploid specific alpha and a specific. Alpha specific are off and need to be turned on, alpha 1 is a positive regulator up regular all. Phosphorylation of proteins, map kinase, kinase kinase, kinase kinase kinase amplifier alpha specific genes. A specific are always on and will have to be repressed. Alpha cell and delete mat alpha phenotype, turns to an a cell. Delete alpha, won"t behave like alpha but a is shut down will not mate properly. Dimerize, shut down alpha specific genes and regulator, cell will behave like a diploid. Mat a or alpha only one on the locus of the cell. Hybrid will inhibit rme, expression of genes, haploid mate but not undergo meiosis. Homothallic single haploid, doesn"t require a mate. Heterothallic stable mat a and can"t complete cycle on own.
