The crystal structure of human replication and transcription cofactor
PC4(CTD) reveals a dimer with two single-stranded (ss)DNA binding chan
nels running in opposite directions to each other. This arrangement su
ggests a role in establishment or maintenance of melted DNA at promote
rs or origins of replication.
