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
