[[http://www.uniprot.org/uniprot/CH3L1_MOUSE CH3L1_MOUSE]] Carbohydrate-binding lectin with a preference for chitin. Has no chitinase activity. May play a role in tissue remodeling and in the capacity of cells to respond to and cope with changes in their environment. Plays a role in T-helper cell type 2 (Th2) inflammatory response and IL-13-induced inflammation, regulating allergen sensitization, inflammatory cell apoptosis, dendritic cell accumulation and M2 macrophage differentiation. Facilitates invasion of pathogenic enteric bacteria into colonic mucosa and lymphoid organs. Mediates activation of AKT1 signaling pathway and subsequent IL8 production in colonic epithelial cells. Regulates antibacterial responses in lung by contributing to macrophage bacterial killing, controlling bacterial dissemination and augmenting host tolerance. Also regulates hyperoxia-induced injury, inflammation and epithelial apoptosis in lung.<ref>PMID:16472595</ref> <ref>PMID:19041398</ref> <ref>PMID:19414556</ref> <ref>PMID:20558631</ref> <ref>PMID:21546314</ref> <ref>PMID:22817986</ref>

== Publication Abstract from PubMed ==
Breast regression protein (BRP39) is a glycoprotein, which is expressed during mammary gland involution in mouse. The physiological function of BRP39 is not known. High levels of expression of BRP39 have also been associated with breast cancer development. In the present investigation a cDNA encoding rBRP39 (recombinant BRP39) was cloned by PCR techniques. It consists of 1,143 nucleotides and encodes an open reading frame of 381 amino acid residues including a signal sequence of 21 amino acids. Recombinant BRP39 was produced in E. coli in a soluble form at low temperature (15 degrees C). Expression and purification of rBRP39 was confirmed by western blot analysis. Purified rBRP39 showed high chitin-binding activity but no chitinase activity. The lack of chitinase activity may be attributed to the mutation of critical active site residue Glu120 to Leu120 and Asp118 to Ala118 in BRP39. However, a mutant in which the residue was reverted back to Glu, by site directed mutagenesis, displayed no chitinase activity. Purified recombinant BRP39 was crystallized and the crystals diffracted X-rays to 2.8A resolution. The crystals belonged to the space group C2 with unit cell parameters a=130.4A, b=81.3A, c=229.2A, beta=105.9 degrees. The structure refinement is in progress.
