摘要: Evidence that many protein regions and even entire proteins lacking stable tertiary and/or secondary structure in solution (i.e., intrinsically disordered proteins) might be involved protein−protein interactions, regulation, recognition, signal transduction is rapidly accumulating. These signaling play a crucial role the development of several pathological conditions, including cancer. To test hypothesis intrinsic disorder also abundant cardiovascular disease (CVD), data set 487 CVD-related was extracted from SWISS-PROT. are depleted major order-promoting residues (Trp, Phe, Tyr, Ile, Val) enriched some disorder-promoting (Arg, Gln, Ser, Pro, Glu). The application neural network predictor natural (PONDR VL-XT) together with cumulative distribution function (CDF) analysis, charge−hydropathy plot (CH plot) α-helical molecular recognition feature (α-MoRF) indicator revealed t...
