What is the function in humans of the protein produced from keratin? -The gene encodes the type1 intermediate filament chain Keratin 17, expressed in nail bed, hair follicle, hwirns, sebaceous glands, and epidermal appendages. - The gene encodes the type1 intermediate filament chain Keratin 17 , expressed in nail ...
What is the function in humans of the protein produced from that gene? The MC1R gene provides instructions for making a protein called the melanocortin 1 receptor. This receptor plays an important role in normal pigmentation.
Holleigh Hollis AP Biology February 1, 2013 Comparing DNA sequences to understand evolutionary relationships with blast DNA 1.What is the function in humans of the protein produced from that gene? Human actin Actins is a highly conserved protein that is involved in cell motility, structure and integrity. Alpha actins are a major constituent of the contractile apparatus.
GAPDH (glyceraldehyde 3-phosphate dehydrogenase) is an enzyme that catalyzes the sixth step in glycolysis, an important reaction that produces molecules used in cellular respiration. The following data table shows the percentage similarity of this gene and the protein it expresses in humans versus other species.
The GUI-O gene codes for an enzyme, L- gulonolactone oxidase, involved in vitamin C synthesis. The GULO gene is present in mice and most other mammals, but is either missing, or is nonfunctional, in some mammals. These animals cannot make their own vitamin C and must have this vitamin present in their diet.

An E-value is the chance that the matchup may be due to a random matching of a sequence of bases. The smaller the E-value, the more confidence you can have in your matching. A good match should have a low E- value (red or pink line) and an alignment along a large segment of the sequence. 13.
In many cases they evolve to the point where a protein can no longer be produced at all. Pseudogenes represent molecular evidence for evolution .
