Protein Domain : Allergen V5/Tpx-1-related, conserved site IPR018244

Type	Conserved_site
Description	The cysteine-rich secretory proteins (Crisp) are predominantly found in the mammalian male reproductive tract as well as in the venom of reptiles. This family includes mammalian testis-specific protein (Tpx-1), also known as cysteine-rich secretory protein 2 (CRISP2) [ ]; venom allergen 5 from vespid wasps and venom allergen 3 from fire ants, which are potent allergens that mediate allergic reactions to stings insects of the Hymenoptera family []; scoloptoxins from Scolopendra dehaani (Thai centipede) []; plant pathogenesis proteins of the PR-1 family [], which are synthesised during pathogen infection or other stress-related responses; allurin, a sperm chemoattractant [], serotriflin [], etc.The precise function of some of these proteins is still unclear. Tpx-1 or CRISP2 may regulate some ion channels' activity and thereby regulate calcium fluxes during sperm capacitation [ ].This entry also includes allergen Tab y 5.0101 from horsefly salivary glands [ ].
