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 ELM2 (EGL-27 and MTA1 homology) domain was first described in Egl-27, a Caenorhabditis elegans protein that plays a fundamental role in patterning during embryonic development [1]. Most ELM2 domain-containing proteins also possess a SANT domain, implying a structural and/or functional relationship between these two motifs. Many proteins containing an ELM2 domain are known components of characterized transcription- and chromatin-regulatory complexes containing one or more histone deacetylases (HDACs). The evolutionarily conserved ELM2 domain has been shown to function as a transcriptional repression domain through recruitment of HDAC activity [2].

Some proteins known to contain a ELM2 domain are listed below:

  • Vertebrate mesoderm induction early response 1 (MI-ER1), a nuclear protein that contains an N-terminal acidic domain with potent transcriptional activity.
  • Vertebrate CoREST, a developmental regulator.
  • Mammalian metastasis-associated protein MTA1, a component of the NURD complex, which has histone deacetylase and ATP-dependent nucleosome remodelling activities.
  • Mammalian metastasis-associated protein MTA2, a component of a chromatin regulatory complex.
  • Mammalian metastasis-associated protein MTA3.
  • Drosophila melanogaster MTA1-like.
  • Drosophila melanogaster GRUNGE (Gug).
  • Drosophila melanogaster transcriptional corepressor Atro.
  • Caenorhabditis elegans Egl-27 and Egr-1. They are redundantly required for embryonic patterning.

The profile we developed covers the entire extended ELM2 domain [2].
