We are deeply saddened by the passing of Amos Bairoch (1957–2025), the creator of PROSITE. We wish to dedicate our latest paper, published shortly before his death, to him. He will always be a source of inspiration to us.
Our deepest condolences go out to his family and friends, and to all those who had the privilege of working with him. Rest in peace, Amos. Your work will live on long after you are gone.

Description

The ~60-residue RAP (an acronym for RNA-binding domain abundant in Apicomplexans) domain is found in various proteins in eucaryotes. It is particularly abundant in apicomplexans and might mediate a range of cellular functions through its potential interactions with RNA [1].

The RAP domain consists of multiple blocks of charged and aromatics residues and is predicted to be composed of α helical and β strand structures. Two predicted loop regions that are dominated by glycine and tryptophan residues are found before and after the central β sheet [1].

Some proteins known to contain a RAP domain are listed below:

  • Human hypothetical protein MGC5297.
  • Mammalian FAST kinase domain-containing proteins (FASTKDs).
  • Chlamydomonas reinhardtii chloroplastic trans-splicing factor Raa3.

The profile we developed covers the entire RAP domain.
