表達(dá)區(qū)間及表達(dá)系統(tǒng)(Source)
Human PSMA, His Tag (PSA-H52H3) is expressed from human 293 cells (HEK293). It contains AA Lys 44 - Ala 750 (Accession # Q04609-1).
Predicted N-terminus: His
蛋白結(jié)構(gòu)(Molecular Characterization)
This protein carries a polyhistidine tag at the N-terminus.
The protein has a calculated MW of 81.4 kDa. The protein migrates as 95-115 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

背景(Background)
前列腺特異性膜抗原(PSMA)也稱為葉酸水解酶1(FOLH1),谷氨酸羧肽酶2(GCP2),N-乙?;?/span>-α-連接的酸性二肽酶I(NAALAD1),屬于肽酶M28家族和M28B亞家族。FOLH1/PSMA在pH值大于6.5時(shí)穩(wěn)定。FOLH1/PSMA是一種II型跨膜鋅金屬肽酶,在神經(jīng)系統(tǒng),前列腺,腎臟和小腸中表達(dá)最高。FOLH1/GCP-2是同型二聚體,每個(gè)亞基結(jié)合2個(gè)鋅離子,是NAALase活性所必需的。PSMA的催化活性涉及釋放未取代的C端谷氨酰殘基,通常來(lái)自Ac-Asp-Glu或葉酸聚γ-谷氨酸。FOLH1/GCP-2/PSMA具有葉酸水解酶和N-乙?;?/span>-α-連接的酸性二肽酶(NAALADase)活性,并且優(yōu)先選擇三α-谷氨酸肽。GCP-2/PSMA參與前列腺腫瘤進(jìn)展,并且還表現(xiàn)出二肽基肽酶IV型活性。在體外,切割Gly-Pro-AMC。
