However, stimulation of mammalian TORC1 by amino acids occurs independently of Tsc1/2 and is mediated instead by a heterodimer of two small GTP-binding protein, consisting of either RagA or RagB and either RagC or RagD.
The first gene, which is separated from P1-rr by 1,175 bp (measured from the end of the 3' P1-rr repeat to the stop codon), encodes the 4Co63-type calmodulin-binding protein consisting of 361 amino acids.
One hybrid protein consists of the DNA binding domain of transcriptional activator LexA fused to a known RNA binding protein bacteriophage MS2 coat protein.
The Transposase protein consists of a DNA binding domain and a catalytic site with the ability to excise and to reinsert the IS DNA sequence into another position, thus moving an IS from one location in the genome to another [ 1, 2].
The family of inhibitors of DNA-binding (ID) proteins consists of four members of basic helix-loop-helix (bHLH) transcription factors lacking the DNA-binding domain (Norton et al, 1998a).
Once ssDNA is generated, it is rapidly bound by the ssDNA-binding-protein RPA, a protein consisting of three subunits: RPA1, RPA2 and RPA3.
HIF1 comprises the binding site for the heterodimeric protein consisting of HIF-1α and the constitutively expressed HIF-1β (also termed ARNT) and is a major regulator of metabolic processes as its activity is controlled by either hypoxia or oxidative stress.
