胱抑素B（英文：Cystatin-B）是一种在人体中由CSTB基因编码的蛋白质。[6][7]

人类地胱抑素B。

胱抑素超家族包括含有多个胱抑素样序列的蛋白质。一些成员是活性半胱氨酸蛋白酶抑制剂，而其他成员已经失去或可能从未获得这种抑制活性。超家族中有3个抑制家族，包括1型胱抑素（stefin）、2型胱抑素和激肽原。该基因编码一种作为细胞内半胱氨酸蛋白酶抑制剂而起作用的stefin。胱抑素B能够形成由非共价作用力稳定的二聚体，抑制木瓜蛋白酶和组织蛋白酶L1、H和B。胱抑素B被认为在防止蛋白酶从溶酶体泄漏方面发挥作用。有证据表明，该基因突变是导致进行性肌阵挛性癫痫患者出现主要缺陷的原因。[7]

交互作用

胱抑素B已被证明与组织蛋白酶B产生交互作用。[8][9]
