The Nucleic Acid Binding Properties Of The Pwi Motif, Hamideh Keshavarz-Mohammadian

Masters Theses

The PWI motif is a highly conserved domain that contains a Proline-Tryptophan-Isoleucine (PWI) tripeptide sequence, for which it is named. Proteins that contain a PWI motif are known to be involved in the constitutive and alternative splicing and the 3'-end processing of messenger RNA transcripts. The hypothesized role of the PWI motif is to nonspecifically interact with nucleic acids. The PWI motif is capable of binding both doublestranded and single stranded forms of DNA and RNA. The structure of the highly conserved core of the PWI motif reveals that it adopts a four-helix bundle fold. The structured core domain, however, …
