NCKX5, a protein involved in the assembly of melanosomes and ultimately in skin coloration

I know Razib and I are both interested in how skin color is determined. Many different genetic loci have been identified as factors in the skin pigmentation biochemical pathway. It can be a mysterious task, but often all it takes is homology in sequences to clue investigators into considering a new loci as a possible... Continue Reading →

The 20,500 Protein-Encoding Genome We Call Our Own

Earlier this week, news of a new paper about the number of protein-encoding genes surfaced on Sandwalk and Henry. The paper's title is straightforward, "Distinguishing protein-coding and noncoding genes in the human genome" but the concepts behind it may not be. As mentioned in Sandwalk, the initial estimates of the number of genes in the... Continue Reading →
