Evolution and variation of multigene families
WebEstimates suggest that gene family evolution may offer an exceptional substrate of genetic variation in M. nervosa, with P sgv = 0.185 compared with P sgv = 0.067 for single nucleotide changes. Hence, we suggest that gene family evolution is a source of 'hopeful monsters' within the genome that may facilitate adaptation when selective pressures ...

WebHigher organisms are complex, and their developmental processes are controlled by the sequential expression of genes that often form multigene families. Facts are surveyed on how functional diversity of genes is related to duplication of genes or segments of genes, by emphasizing that diversity is often enhanced by alternate splicing and proteolytic … WebMultigene Family. A set of genes descended by duplication and variation from some ancestral gene. Such genes may be clustered together on the same chromosome or dispersed on different chromosomes. Examples of multigene families include those that encode the hemoglobins, immunoglobulins, histocompatibility antigens, actins, tubulins, …

Search for more articles by this author WebMultigene families such as var, rifin, stevor, and pfmc-2tm [155] are the major cause of antigenic variation in P. falciparum infection. Extremely small subsets of genes within these families are expressed with the others members are kept transcriptionally silent.
