Baculoviral IAP repeat-containing protein 1 or neuronal apoptosis inhibitory protein (NAIP) is an anti-apoptotic protein which acts by inhibiting the activities of CASP3, CASP7 and CASP9. NAIP contains three baculoviral IAP repeat (BIR) domains at the amino-terminal region and a ATP/GTP binding site []. NAIP has been shown to inhibit apoptosis in neurons []and in several mammalian cell lines [].
