BIR stands for 'Baculovirus Inhibitor of apoptosis protein Repeat'. It is found repeated in inhibitor of apoptosis proteins (IAPs), and in fact it is also known as IAP repeat. These domains characteristically have a number of invariant residues, including 3 conserved cysteines and one conserved histidine that coordinate a zinc ion. They are usually made up of 4-5 alpha helices and a three-stranded beta-sheet. BIR is also found in other proteins known as BIR-domain-containing proteins (BIRPs), such as Survivin (Swiss:O15392) [2].	Domain
A	PF17889	NLRC4 helical domain (NLRC4_HD)	NLRC4 helical domain	This is a helical domain found in NLRC4 , Nucleotide-binding and oligomerization domain-like receptor (NLR) proteins. Structural and functional studies indicate that the helical domain HD2 repressively contacted a conserved and functionally important ...	This is a helical domain found in NLRC4 , Nucleotide-binding and oligomerization domain-like receptor (NLR) proteins. Structural and functional studies indicate that the helical domain HD2 repressively contacted a conserved and functionally important alpha-helix of the NBD (nucleotide binding domain) in Swiss:Q3UP24. Furthermore, the HD2 domain was shown to cap the N-terminal side of the LRR (leucine-rich repeat) domain via extensive interactions [1]. Other family members carrying this domain include baculoviral IAP repeat-containing protein 1 (Birc1) also known as neuronal apoptosis inhibitory protein (Naip).	Domain
