General annotation (Comments)

Function

Required for optimal DNA polymerase delta activity. May contribute to PCNA-dependent activity of DNA polymerase delta. Ref.6

Subunit structure

Heterotetramer composed of subunits of 125 kDa, 50 kDa, 66 kDa and 12 kDa. Interacts with WRNIP1. Interacts with POLD4, POLD2, POLD1 and PCNA. Ref.5 Ref.6

Subcellular location

Nucleus.

Sequence similarities

Belongs to the DNA polymerase delta subunit 4 family.

Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]
Isoform 1 (identifier: Q9HCU8-1)

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.
Isoform 2 (identifier: Q9HCU8-2)

The sequence of this isoform differs from the canonical sequence as follows:
     63-107: GITRLQRWCRAKQMGLEPPPEVWQVLKTHPGDPRFQCSLWHLYPL → VSGISIPYEAPRKTSCP
Note: No experimental confirmation available.
