The enzyme is characterized by the ability to catalyze the conversion of cephalosporin C, gultaryl 7-ACA, apidyl 7-ACA, succinyl 7-ACA, N-acetylcephalosporin C, N-benzoylcephalosporin C, and cephalothin into 7-aminocephalosporanic acid and is composed of an .alpha.-subunit with a molecular weight of 26,000 daltons and a .beta.-subunit with a molecular weight of 58,000 daltons.
摘要:
The present invention relates to the novel isoforms, RXRα2 and RXRα3, of nuclear receptor RXRα. Unlike known isoform RXRα1, the transcriptional activation functions of RXRα2 and RXRα3 are augmented by SRC-1. The present invention provides methods for evaluating the function of regulating augmentation by co-activators of these RXRα isoforms, and screening methods based on these evaluation methods. By controlling the interaction between isoforms and co-activators, transcription-controlling activity can be regulated in an isoform-specific manner.
摘要:
The present invention relates to novel nuclear receptor ERRγ3. Although ERRγ3 itself lacks a DNA binding domain, it comprises the function of enhancing the transcriptional activation function of arbitrary nuclear receptors, such as ERR, ER, or TR. Moreover, the present inventors found that, like ERRγ3, the known proteins ERRγ1 and ERRγ2 also comprise the function of enhancing the transcriptional activation function of other nuclear receptors. Thus, the present invention provides methods for evaluating the regulatory function of these ERRγ subtypes in enhancing the transcriptional activation function of other nuclear receptors, and screening methods based on these evaluation methods.
