Temporal scaling of molecular evolution in primates and other mammals.

abstract：:Although evolutionary studies of gene function often rely on RNA interference, the ideal approach would use reverse genetics to create null mutations for cross-species comparisons and forward genetics to identify novel genes in each species. We have used transcription activator-like effector nucleases (TALENs) to faci...

abstract：:This study describes the origin and structural features of a mammalian gene, CGIN1 (Cousin of GIN1). CGIN1 proteins contain an NYN domain, retroviral RNase H and integrase domains, and a domain of unknown function (CGIN1 domain) that is also present in two other genes (N4BP1 and KIAA0323). We suggest that CGIN1 derive...
