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].

PF17889NLRC4 helical domain (NLRC4_HD)NLRC4 helical domainThis 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).
