Outline: -Discuss Primary Structure[ -Discuss Secondary Structure -Comprised of alpha helices and 1 beta sheet -Discuss tertiary structure -No quaternary structure -427 amino acids, 48289 Da (http://www.genecards.org/cgi-bin/carddisp.pl?gene=VDR)

Protein 1db1 is found to complex with 1,25 Dihydroxy . This molecule has three notable alcohol groups that have the ability to participate in interactions with the protein. Vitamin D3 has a large number of relations with the residues on the protein chain. First in the sequence are . Tyr143, shown in blue, is the closest to the ligand at 2.83 angstroms. This is sightly large but there is still the possibility of hydrogen bonding. Tyr147 in green and Phe150 in black are also known to have interactions with Vitamin D3 they are farther away and therefore less significant. Outline: as has been started, the interactions of the various residues will be covered. The types of bonds that 1db1 and VDX form will be elaborated as well
Additional FeaturesAdditional Features

A mutation in the transcription of the protein has the potential to result in the disease known as type 2 rickets. The mutation results in the not forming properly. Therefore VDR cannot complex with VDX. Outline: -Discuss mutations in Vitamin D receptor (Rickets) -Regulating hair cycle -Examine attempts to regulate Vitamin D receptor
Quiz Question 1Quiz Question 1
|
Quiz question: More information is needed to focus what the quiz should be about. Possibly related to how the secondary structure is comprised almost entirely of alpha helices, and how that relates to the amino acid sequences.
