As a likely component of a histone deacetylase complex, together with saeg-2 and hda-2, functions downstream of the cAMP-dependent kinase egl-4 to regulate the expression of genes required for egg-laying and foraging. May be a component of a histone deacetylase complex containing saeg-2, saeg-1 and hda-2. May interact with egl-4. Ubiquitously expressed.
