leucine-rich repeats, ribonuclease inhibitor (RI)-like subfamily. A leucine-rich repeat (LRR) is a structural protein motif of 20-30 amino acids that is unusually rich in the hydrophobic amino acid leucine. The conserved eleven-residue sequence motif (LxxLxLxxN/CxL) within the LRRs corresponds to the beta-strand and adjacent loop regions, whereas the remaining parts of the repeats are variable. LRRs fold together to form a solenoid protein domain, termed leucine-rich repeat domain. Leucine-rich repeats are usually involved in protein-protein interactions.
class 1 internalin InlA. Internalins, as found in the intracellular human pathogen Listeria monocytogenes, are paralogous surface or secreted proteins with an N-terminal signal peptide, leucine-rich repeats, and usually a C-terminal LPXTG processing and cell surface anchoring site. See PMID:17764999 for a general discussion of internalins. Members of this family are internalin A (InlA), a class 1 (LPXTG-type) internalin.

NEAT domain-containing leucine-rich repeat protein. Members of this family have an N-terminal NEAT (near transporter) domain often associated with iron transport, followed by a leucine-rich repeat region with significant sequence similarity to the internalins of Listeria monocytogenes. However, since Bacillus cereus (from which this protein was described, in PMID:16978259) is not considered an intracellular pathogen, and the function may be iron transport rather than internalization, applying the name "internalin" to this family probably would be misleading.
