Cathepsin D 蛋白, Human (HEK293, His, solution)

Cathepsin D Protein, Human (HEK293, His, solution) is an approximately 50.0 kDa cathepsin D protein with a His-flag. Cathepsin D is a representative lysosomal aspartic proteinases and belongs to the peptidase C1 family^[1].

组织蛋白酶 D (CTSD) 是一种著名的溶酶体天冬氨酰蛋白酶，属于肽酶 C1 家族，是溶酶体的正常主要成分，几乎存在于哺乳动物的所有细胞和组织中^[1]。
人组织蛋白酶 D 作为前体蛋白合成，由信号肽（残基 1-18）、前肽（残基 1964）和成熟链（残基 (65412)）组成^[2]。

Measured by its ability to cleave the fluorogenic peptide substrate, Mca-PLGL-Dpa-AR-NH2. The specific activity is >600 pmol/min/µg, as measured under the described conditions.
