Defective gamma-carboxylation of F9

Reactome ID: R-HSA-9673240

中文名称

缺陷F9γ-羧基化

通路描述

自然发生的血友病B(HB)相关点突变在FIX前肽序列中降低与γ-谷氨酰羧基酶(GGCX)的结合亲和力,导致γ-羧基化减少和异常前肽加工(Bentley AK等,1986;Rabiet MJ等,1987;Diuguid DL等,1986;Ware J等,1989;de la Salle C等,1993)。未加工的FIX变体如F9 N43Q/L或F9 N46S,与附着的前肽一起循环,并显示延迟的FIX激活(Bentley AK等,1986;Diuguid DL等,1986;Ware J等,1989;de la Salle C等,1993)。
英文描述
Defective gamma-carboxylation of F9 Naturally occurring hemophilia B (HB)-associated point mutations in the FIX propeptide sequence reduce affinity to gamma-glutamyl carboxylase (GGCX) resulting in reduced γ-carboxylation and aberrant propeptide processing (Bentley AK et al. 1986; Rabiet MJ et al. 1987; Diuguid DL et al. 1986; Ware J et al. 1989; de la Salle C et al. 1993). Unprocessed FIX variants such as F9 N43Q/L or F9 N46S, circulate with the attached propeptide and show delayed FIX activation (Bentley AK et al. 1986; Diuguid DL et al. 1986; Ware J et al. 1989; de la Salle C et al. 1993).
