BHLH-PAS Proteins: Their Structure and Intrinsic Disorder.

ABSTRACT: The basic helix-loop-helix/Per-ARNT-SIM (bHLH-PAS) proteins are a class of transcriptional regulators, commonly occurring in living organisms and highly conserved among vertebrates and invertebrates. These proteins exhibit a relatively well-conserved domain structure: the bHLH domain located at the N-terminus, followed by PAS-A and PAS-B domains. In contrast, their C-terminal fragments present significant variability in their primary structure and are unique for individual proteins. C-termini were shown to be responsible for the specific modulation of protein action. In this review, we present the current state of knowledge, based on NMR and X-ray analysis, concerning the structural properties of bHLH-PAS proteins. It is worth noting that all determined structures comprise only selected do
