RPEL repeat (IPR004018)

Short name: RPEL_repeat


RPEL repeat (RPxxxEL) containing proteins are found in a wide range of metazoan organisms. RPEL repeats have been shown to be required for unpolymerised actin binding and proteins containing RPEL repeats are able to modify cell shape and/or are important in the regulation of gene expression by the actin cytoskeleton. RPEL repeats can be found in association with the SAP motif, which could be involved in DNA binding [PMID: 12732141, PMID: 15620697].

Some proteins known to contain RPEL repeats are listed below:

  • Mammalian myocardin, heart-specific serum response factor (SRF) co- activator.
  • Vertebrate myocardin-related transcription factor A (MRTF-A or MAL), a signal-regulated SRF co-activator.
  • Vertebrate myocardin-related transcription factor B (MRTF-B).
  • Mammalian phosphatase and actin regulator 1 to 3.
