Identification by yeast two-hybrid screening of proteins that interact with human nuclear RNase P protein subunits

Bait	Prey	Interacting partner
Rpp20	Hela cell cDNA library*	Small heat shock protein 27 (Hsp27)KIAA0615 (unknown function)
Rpp14		Human LIM domain-containing gene (LIMD1)OIP2 [Neisseria gonorrheae opacity-associated (Opa) protein interacting protein]
		HSPC232 (unknown function)
		Novel sequence (unknown function)
Rpp30		Rpp14
Rpp21†		No strongly interacting partner
Rpp29
Rpp38
Rpp40
hpop1

^*The prey in every case was a HeLa cell cDNA library. 

^† The remaining proteins listed below had no strongly interacting partners.
