RelA-associated inhibitor (PPP1R13L)

Regulator that plays a central role in regulation of apoptosis and transcription via its interaction with NF-kappa-B and p53/TP53 proteins. Blocks transcription of HIV-1 virus by inhibiting the activity of both NF-kappa-B and SP1.

Also inhibits p53/TP53 feature, possibly by preventing the association between p53/TP53 and ASPP1 or ASPP2, and so suppressing the subsequent activation of apoptosis. .
