PEST proteolytic signal-containing nuclear protein (IPR029169)

Short name: PCNP

Family relationships

None.

Description

PCNP is a PEST-containing nuclear protein that is ubiquitinated by NIRF, a Np95/ICBP90-like RING finger protein probably involved in cell cycle regulation [PMID: 12176013]. PEST sequences, which are rich in proline (P), glutamic acid (E), serine (S) and threonine (T), are found in a number of short-lived proteins, such as transcription factors and cell cycle-associated proteins. Their function is generally controlled by proteolysis, mostly via ubiquitin-mediated degradation [PMID: 14741369]. NIRF and PCNP may constitute a novel signaling pathway with some relation to cell proliferation.
