40S ribosomal protein S16

40S ribosomal protein S16 is a protein that in humans is encoded by the RPS16 gene. This protein is a component of the 40S subunit of the ribosome, which is essential for protein synthesis in all living organisms. The RPS16 gene is located on chromosome 19 in humans.

Structure

40S ribosomal protein S16 is a small protein consisting of 116 amino acids. It plays a crucial role in the assembly and function of the 40S ribosomal subunit. The protein contains a conserved S16 domain that is important for its interaction with other ribosomal proteins and ribosomal RNA.

Function

As a component of the 40S subunit, 40S ribosomal protein S16 is involved in the decoding of messenger RNA (mRNA) during translation. It helps to position the mRNA on the ribosome and ensures accurate reading of the genetic code to synthesize proteins.

Clinical Significance

Mutations in the RPS16 gene have been associated with certain genetic disorders and diseases. Dysregulation of ribosomal proteins, including 40S ribosomal protein S16, can lead to abnormal protein synthesis and contribute to various pathological conditions.

Interactions

40S ribosomal protein S16 interacts with other ribosomal proteins, ribosomal RNA, and translation factors to form the functional ribosome complex. These interactions are essential for the proper assembly and activity of the ribosome during protein synthesis.
