Table 1. Potential CDK5-binding partners identified from yeast two-hybrid screening.

GenBank accession No.	Prey protein	Prey redundancy
XP_42059	Cyclin I (CCNI)	3
XP_001234830	Cyclin I-like (CCNI2)	2

CDK5 was used as bait to screen a chick cochlear cDNA library. Totally five positive clones were obtained, encoding CCNI and CCNI2.
