A new protein factor named PF2 was recently isolated from mammalian cell nuclei. Among other protein domains, PF2 exhibits an RPD3-interacting domain (RPD3 contains the catalytic activity of the HDAC B complex) and a TFS-interacting domain (TFS is a DNA binding protein). PF2 does not have a DNA binding domain, however. Predict a likely function of PF2 and justify it. The importance of both domains should be explained.

The likely functions of  PF2 includes binding of several protein factors and DNA structure formation

Explanation:

PF2 contains RPD3 and TFS domains

The likely functions of  PF2 includes binding and DNA structure formation

For the RPD3 domain that contains the  catalytic activity of the HDAC B complex its function is to interact with other protein factors by binding with them and carrying out the  process of the signaling cascade.

while the TFS - interacting domain have likely functions like ; DNA replication, DNA repair and storage. It also has the function involving the DNA structure

answer; i believe its (ovulation);

im not in connections yet but i might can you some questions. what grade are you in?
