==Mutation==
Amino acids like serine and threonine kinase plays a crucial role in signal transduction pathways drawn out by variety of growth factors, hormones, and neurotransmitters. When <scene name='56/562378/Vit_d_receptor_3m7r_serine/5'>serine</scene> is mutated it is replaced with a <scene name='56/562378/Vit_d_receptor_3m7r_serine/8'>glycine</scene> which results in an inhibition of transcriptional activation. When transcription is inhibited it results in p53 accumulation, which activates and promotes p53 translocation into mitochondria leading to apoptosis. Transcription inhibition is useful in cancer patients and so can be used as treatment option.

<scene name='56/562378/Vit_d_receptor_3m7r_serine/9'>aspartic acid</scene> when mutated creating a negative charge. The negative charge at the residue inhibits DNA binding which cause a down – regulation of VDR activity. VDR needs DNA binding in order for it to be activated which is only possible with a serine residue.
