PROSITE documentation PDOC01013

Uncharacterized protein family UPF0057 signature





Description

The following uncharacterized proteins have been shown [1] to be evolutionary related:

  • Barley low-temperature induced protein blt101.
  • Lophorium elongatum salt-sress induced protein ESI3.
  • Yeast hypothetical proteins YDL123w, YDR276c, YDR525Bw and YJL151c.
  • Caenorhabditis elegans hypothetical proteins F47B7.1, T23F2.3, T23F2.4, T23F2.5 and ZK632.10.
  • Escherichia coli hypothetical protein yqaE.
  • Synechocystis strain PCC 6803 hypothetical protein ssr1169.

These are small proteins of from 52 to 140 amino-acid resiudes that contains two transmembrane domains. As a signature pattern we selected a region that corresponds to the end of the first transmembrane helix.
