TATA-binding protein (TBP)-associated factor 7l (Taf7l; a paralogue of Taf7) and TBP-related factor 2 (Trf2) are components of the core promoter complex required for gene/tissue-specific transcription of protein-coding genes by RNA polymerase II. Previous studies reported that Taf7l knockout (KO) mice exhibit structurally abnormal sperm, reduced sperm count, weakened motility, and compromised f...

means of the well-known method of irradiation followed by testing with BTfecessive-marker stocks, many visible mutants at specific loci have been obtained in mice by several investigators. In some instances the mutants so obtained are presumably identical with the markers employed in the tester stock, but very often distinctive new alleles are involved. These latter may be of intrinsic interest...

A y is an e voluti onari ly conserved self‐digestion process which is essential to keep basal homeostasis in a cell. During this process, degradation and recycling of many cytoplasmic components including the long‐lived, unnecessary or aggregated proteins and damaged organelles is achieved through lysosomal machinery. Autophagy has a critical role for lower eukaryotic organisms such as yeast to...
