Predicting the effects of the single nucleotide polymorphism A122V on CXC chemokine receptor type 1 of Bos taurus (Artiodactyla: Bovidae) cattle by in silico analyses

Abstract: Este estudo objetivou predizer bioquimicamente as estruturas primárias e secundárias da proteína receptora de quimiocina CXCR1 bovina não polimórfica e polimórfica carreando o polimorfismo A122V por análises in silico. Duas sequências da proteína CXCR1 de bovino Bos taurus foram selecionadas a partir da base de dados de sequências de proteínas UniProtKB/Swiss-Prot: a) uma sequência não polimórfica (A7KWG0), contendo o aminoácido alanina (A) na posição 122, e b) uma sequência polimórfica, apresentando o aminoác… Show more

“…Thus, although remarkable differences in the distance between pairs of amino acid residues are inferred resulting from A122V polymorphism, both predictive CXCR1 models safely demonstrated high local quality and acceptable structural accuracy. Recently, Guzzi et al (2017) examined the secondary structure pattern of the bovine A122V-harboring CXCR1 protein, revealing the absence of an alpha helix domain between positions 100 and 150, as possible consequence of the replacement of alanine with high helix-forming propensity by valine with limited helix-forming propensity in the polymorphic protein. Notably, diverse functions of the proteins are directly associated with their appropriate structural folding resulting from physical interactions among their amino acid residues.…”
