Protein Family Models

The S1 domain occurs in a wide range of RNA associated proteins. It is structurally similar to cold shock protein which binds nucleic acids. The S1 domain has an OB-fold structure. Structure and an extension of S1 family. [1]. 9008164. The solution structure of the S1 RNA binding domain: a member of an ancient nucleic acid-binding fold.

30S ribosomal protein S1 is required for translation of most natural mRNAs except for leaderless mRNA; it binds mRNA upstream of the Shine-Dalgarno (SD) sequence and helps it bind to the 30S ribosomal subunit

Involved in binding to the leader sequence of mRNAs and is itself bound to the 30S subunit; autoregulates expression via a C-terminal domain; in most gram negative organisms this protein is composed of 6 repeats of the S1 domain while in gram positive there are 4 repeats; the S1 nucleic acid-binding domain is found associated with other proteins
