Ribonuclease T2-A; Has ribonuclease activity, with higher activity at acidic pH. May play a role in cellular RNA catabolism. Probably is involved in lysosomal degradation of ribosomal RNA.

Membrane-spanning 4-domains subfamily A member 3; Hematopoietic modulator for the G1-S cell cycle transition. Modulates the level of phosphorylation of cyclin-dependent kinase 2 (CDK2) through its direct binding to cyclin-dependent kinase inhibitor 3 (CDKN3/KAP) (By similarity).

Chitinase-like protein 3; Lectin that binds saccharides with a free amino group, such as glucosamine or galactosamine. Binding to oligomeric saccharides is much stronger than binding to mono- or disaccharides. Also binds chitin and heparin. Has weak hexosaminidase activity but no chitinase activity. Has chemotactic activity for T-lymphocytes, bone marrow cells and eosinophils. May play a role in inflammation and allergy.

Probable inactive ribonuclease-like protein 12; Does not exhibit any ribonuclease activity; Belongs to the pancreatic ribonuclease family.

Putative inactive ribonuclease 11.

Ribonuclease inhibitor; Ribonuclease inhibitor which inhibits RNASE1, RNASE2 and ANG. May play a role in redox homeostasis (By similarity).

Myeloperoxidase heavy chain; Part of the host defense system of polymorphonuclear leukocytes. It is responsible for microbicidal activity against a wide range of organisms. In the stimulated PMN, MPO catalyzes the production of hypohalous acids, primarily hypochlorous acid in physiologic situations, and other toxic intermediates that greatly enhance PMN microbicidal activity; Belongs to the peroxidase family. XPO subfamily.

Eosinophil peroxidase heavy chain; Mediates tyrosine nitration of secondary granule proteins in mature resting eosinophils; Belongs to the peroxidase family. XPO subfamily.
