KRT83 KRT83 Keratin 83, also known as KRT83, is a protein which humans is encoded by the "KRT83" gene. The protein encoded by this gene is a member of the keratin gene family. As a type II hair keratin, it is a basic protein which heterodimerizes with type I keratins to form hair and nails. The type II hair keratins are clustered in a region of chromosome 12q13 and are grouped into two distinct subfamilies based on structure similarity. One subfamily, consisting of KRTHB1 (KRT81), KRTHB3 (KRT83, this protein), and KRTHB6 (KRT86), is highly related. The other less-related subfamily includes KRTHB2
Ribosomal protein leader form an intrinsic transcription termination stem-loop. When cellular concentrations of the ribosomal protein are not high, they are occupied in the ribosome, and are not available in significant quantities to bind the mRNA leader. This leads to increased expression of the gene, which leads to the synthesis of more copies of the ribosomal protein. Many examples of ribosomal protein leaders are known in bacteria, including ribosomal protein L20 leader and ribosomal S15 leader. Ribosomal protein leader A ribosomal protein leader is a mechanism used in cells to control the cellular concentration of a protein that forms a part of the
