RCC1 and BTB domain-containing protein 1; May be involved in cell cycle regulation by chromatin remodeling.

Integral membrane protein 2B; Plays a regulatory role in the processing of the amyloid-beta A4 precursor protein (APP) and acts as an inhibitor of the amyloid-beta peptide aggregation and fibrils deposition. Plays a role in the induction of neurite outgrowth. Functions as a protease inhibitor by blocking access of secretases to APP cleavage sites. Bri23 peptide prevents aggregation of APP amyloid-beta protein 42 into toxic oligomers; Belongs to the ITM2 family.

NudC domain-containing protein 2; May regulate the LIS1/dynein pathway by stabilizing LIS1 with Hsp90 chaperone.

Fibronectin type-III domain-containing protein 3A; Mediates spermatid-Sertoli adhesion during spermatogenesis. Belongs to the FNDC3 family.

Ubiquitin-conjugating enzyme E2 E3; Accepts ubiquitin from the E1 complex and catalyzes its covalent attachment to other proteins. In vitro catalyzes 'Lys-11'- and 'Lys-48'-, as well as 'Lys-63'-linked polyubiquitination. Participates in the regulation of transepithelial sodium transport in renal cells. May be involved in cell growth arrest.

Cytidine and dCMP deaminase domain-containing protein 1; May play an important role in testicular development and spermatogenesis; Belongs to the cytidine and deoxycytidylate deaminase family.

Histone-lysine N-methyltransferase SETDB2; Histone methyltransferase involved in left-right axis specification in early development and mitosis. Specifically trimethylates 'Lys-9' of histone H3 (H3K9me3). H3K9me3 is a specific tag for epigenetic transcriptional repression that recruits HP1 (CBX1, CBX3 and/or CBX5) proteins to methylated histones. Contributes to H3K9me3 in both the interspersed repetitive elements and centromere- associated repeats. Plays a role in chromosome condensation and segregation during mitosis.

Cysteinyl leukotriene receptor 2; Receptor for cysteinyl leukotrienes. The response is mediated via a G-protein that activates a phosphatidylinositol-calcium second messenger system. Stimulation by BAY u9773, a partial agonist, induces specific contractions of pulmonary veins and might also have an indirect role in the relaxation of the pulmonary vascular endothelium. The rank order of affinities for the leukotrienes is LTC4 = LTD4 >> LTE4.

Testis-specific serine/threonine-protein kinase 4; Serine/threonine kinase which is involved in male germ cell development and in mature sperm function (By similarity). May be involved in the Cre/Creb signaling pathway (By similarity). Phosphorylates CREB1 on 'Ser-133' in vitro and can stimulate Cre/Creb pathway in cells. Phosphorylates CREM on 'Ser-116' in vitro (By similarity). Phosphorylates ODF2 on 'Ser-95' (By similarity). Belongs to the protein kinase superfamily. CAMK Ser/Thr protein kinase family.
