Transcription factor PU.1; Binds to the PU-box, a purine-rich DNA sequence (5'-GAGGAA- 3') that can act as a lymphoid-specific enhancer. This protein is a transcriptional activator that may be specifically involved in the differentiation or activation of macrophages or B-cells. Also binds RNA and may modulate pre-mRNA splicing.

Murinoglobulin-1; A proteinase activates the inhibitor by specific proteolysis in the bait region, which, by an unknown mechanism leads to reaction at the cysteinyl-glutamyl internal thiol ester site and to a conformational change, whereby the proteinase is trapped and/or covalently bound to the inhibitor. While in the tetrameric proteinase inhibitors steric inhibition is sufficiently strong, monomeric forms need a covalent linkage between the activated glutamyl residue of the original thiol ester and a terminal amino group of a lysine or another nucleophilic group on the proteinase, f [...]

Truncated apolipoprotein A-I; Participates in the reverse transport of cholesterol from tissues to the liver for excretion by promoting cholesterol efflux from tissues and by acting as a cofactor for the lecithin cholesterol acyltransferase (LCAT). As part of the SPAP complex, activates spermatozoa motility; Belongs to the apolipoprotein A1/A4/E family.

Carboxylesterase 3B; Involved in the detoxification of xenobiotics and in the activation of ester and amide prodrugs; Belongs to the type-B carboxylesterase/lipase family.

Murinoglobulin-2; A proteinase activates the inhibitor by specific proteolysis in the bait region, which, by an unknown mechanism leads to reaction at the cysteinyl-glutamyl internal thiol ester site and to a conformational change, whereby the proteinase is trapped and/or covalently bound to the inhibitor.

Carboxylesterase 3A; Involved in the detoxification of xenobiotics and in the activation of ester and amide prodrugs; Belongs to the type-B carboxylesterase/lipase family.

Major urinary protein 20; Male pheromone which stimulates female sexual attraction to male urinary scent and promotes a strong learned attraction to the airborne urinary odor of an individual male. Promotes male aggressive behavior. Binds most of the male pheromone, 2-sec-butyl-4,5- dihydrothiazole, in urine; Belongs to the calycin superfamily. Lipocalin family.

Estradiol 17 beta-dehydrogenase 5; Active toward androgens, estrogens, and xenobiotic substrates. Also exhibits low 20 alpha-HSD activity. Shows a- stereospecificity in hydrogen transfer between cofactors and substrates (A-specific). Preferentially catalyzes the reduction of 4- androstenedione, 5-alpha-androstane-3,17-dione, androsterone and dehydroepiandrosterone to testosterone, dihydrotestosterone, 5-alpha- androstane-3-alpha,17-beta-diol and 5-androstene-3-beta,17-beta-diol, respectively; Belongs to the aldo/keto reductase family.
