Mammalian circadian autoregulatory loop: a timeless ortholog and mPer1 interact and negatively regulate CLOCK-BMAL1-induced transcription.
Isolation of timeless by PER protein interaction: defective interaction between timeless protein and long-period mutant PERL.
Histidine residues regulate the transition of photoexcited rhodopsin to its active conformation, metarhodopsin II.
Production of bovine rhodopsin by mammalian cell lines expressing cloned cDNA: spectrophotometry and subcellular localization.
