However, how and why these two major types of regulatory mutations arise in different genes and how gene expression is inherited and associated with these regulatory changes are unclear. Trans-acting factors can be categorized by their interactions with the regulated genes, cis-acting elements of the genes, or the gene products. DNA binding trans-acting factors regulate gene expression by interfering with the gene itself or cis-acting elements of the gene, which lead to changes in transcription activities.

WebJan 2, 2011 · A third case had mutated nucleotides T at the first and second positions of codon 12, which could represent a double mutation ( cis, GGT > TTT in 1 allele with amino acid Gly > Lys) or 2 independent mutations, 1 on each allele ( trans, GGT > TGT and GGT > GTT with amino acids Gly > Cys and Gly > Val). WebA loss-of-function mutation of a cis-acting operator can be dominant to wild type, in a diploid genotype. Cis-acting elements may be sites for either positive or negative regulation If a trans-acting regulator is transposed to a different chromosome, the expression of the genes that it regulates will not change.
