Prostate and testis expressed 2.

Prostate and testis expressed 1; Belongs to the PATE family.

Ly-6/neurotoxin-like protein 1; Acts in different tissues through interaction to nicotinic acetylcholine receptors (nAChRs). The proposed role as modulator of nAChR activity seems to be dependent on the nAChR subtype and stoichiometry, and to involve an effect on nAChR trafficking and its cell surface expression, and on single channel properties of the nAChR inserted in the plasma membrane. Modulates functional properties of nicotinic acetylcholine receptors (nAChRs) to prevent excessive excitation, and hence neurodegeneration. Enhances desensitization by increasing both the rate and e [...]

Secreted Ly-6/uPAR-related protein 1; Has an antitumor activity. Was found to be a marker of late differentiation of the skin. Implicated in maintaining the physiological and structural integrity of the keratinocyte layers of the skin. In vitro down-regulates keratinocyte proliferation; the function may involve the proposed role as modulator of nicotinic acetylcholine receptors (nAChRs) activity. In vitro inhibits alpha-7-dependent nAChR currents in an allosteric manner. In T cells may be involved in regulation of intracellular Ca(2+) signaling. Seems to have an immunomodulatory functi [...]

Ly6/PLAUR domain-containing protein 6; Acts as a modulator of nicotinic acetylcholine receptors (nAChRs) function in the brain. Inhibits nicotine-induced Ca(2+) influx through nAChRs. Acts as a positive regulator of Wnt/beta-catenin signaling (By similarity).

Ly6/PLAUR domain-containing protein 6B; Believed to act as a modulator of nicotinic acetylcholine receptors (nAChRs) activity. In vitro acts on nAChRs in a subtype- and stoichiometry-dependent manner. Modulates specifically alpha-3(3):beta- 4(2) nAChRs by enhancing the sensitivity to ACh, decreasing ACh-induced maximal current response and increasing the rate of desensitization to ACh; has no effect on alpha-7 homomeric nAChRs; modulates alpha- 3(2):alpha-5:beta-4(2) nAChRs in the context of CHRNA5/alpha-5 variant Asn-398 but not its wild-type sequence.

Secreted Ly-6/uPAR domain-containing protein 2; Binds and may modulate the functional properties of nicotinic and muscarinic acetylcholine receptors. May regulate keratinocytes proliferation, differentiation and apoptosis. In vitro moderately inhibits ACh-evoked currents of alpha-3:beta-2-containing nAChRs and strongly these of alpha-4:beta-2-containing nAChRs, modulates alpha-7- containing nAChRs, and inhibits nicotine-induced signaling probably implicating alpha-3:beta-4-containing nAChRs. Proposed to act on alpha- 3:beta-2 and alpha-7 nAChRs in an orthosteric, and on mAChRs, such as [...]

Protein-glutamine gamma-glutamyltransferase 4; Associated with the mammalian reproductive process. Catalyzes the cross-linking of proteins and the conjugation of polyamines to specific proteins in the seminal tract.
