Switch #: SWTI000316

Switch type: Specificity

Switch subtype: Motif hiding

Description:
Inhibition of nuclear import of DNA polymerase processivity factor (UL44) by phosphorylation-dependent (T427) binding of BRCA1-associated protein (BRAP).

Participants:
(1) DNA polymerase processivity factor (UL44)
(2) BRCA1-associated protein (BRAP)
(3) Importin subunit alpha-1 (KPNA1)

(1) The BRCA-1 binding protein BRAP2 is a novel, negative regulator of nuclear import of viral proteins, dependent on phosphorylation flanking the nuclear localization signal.

(2) Identification of a novel cytoplasmic protein that specifically binds to nuclear localization signal motifs.
