- * Proliferating cell nuclear antigen signature *
- ************************************************
-
- Proliferating cell nuclear antigen (PCNA) [1,2] is a protein involved in DNA
- replication by acting as a cofactor for DNA polymerase delta, the
- polymerase responsible for leading strand DNA replication.
-
- A similar protein exists in yeast (gene POL30) [3] and is associated with
- polymerase III, the yeast analog of polymerase delta. In baculoviruses the
- ETL protein has been shown [4] to be highly related to PCNA and is probably
- associated with the viral encoded DNA polymerase.
-
- As a signature for this family of proteins, we selected a conserved region
- located in the N-terminal section, which has been proposed to bind DNA.

- -Consensus pattern: R-C-D-[RH]-x(3)-[LIVM]-x(3)-[LIVM]-x-[SAN]-[LIVM]-x-K-

- -Sequences known to belong to this class detected by the pattern: ALL.
- -Other sequence(s) detected in SWISS-PROT: NONE.
