The LisH domain is found in Sif2, a component of the Set3 complex which is responsible for repressing meiotic genes. It has been shown that the LisH domain helps mediate interaction with components of the Set3 complex [1].

The Spt20 protein is part of the SAGA complex which is a large complex mediating histone deacetylation. Yeast Spt20 has been shown to play a role in structural integrity of the SAGA complex as as no intact SAGA could be purified in spt20 deletion strains [1]. Spt20 is indispensable under endoplasmic reticulum (ER) stress conditions, being involved in the regulation of stress-responsive genes transcription. This domain interacts with LisH motif helices of Taf5 [2,3].

A number of them are thought to carry a distinctive five-residue motif termed the proteasome-interacting motif (PIM), which may have a biologically significant role in protein delivery to proteasomes and recruitment of proteasomes to transcription sites [5].
