Dec 25, 2024 · PDE6B (Phosphodiesterase 6B) is a Protein Coding gene. Diseases associated with PDE6B include Retinitis Pigmentosa 40 and Night Blindness, Congenital Stationary, Autosomal Dominant 2. Among its related pathways are Visual phototransduction and Autodegradation of the E3 ubiquitin ligase COP1.

Rod cGMP-specific 3',5'-cyclic phosphodiesterase subunit beta is the beta subunit of the protein complex PDE6 that is encoded by the PDE6B gene. [5][6] PDE6 is crucial in transmission and amplification of visual signal. The existence of this beta subunit is …

The PDE6B gene provides instructions for making a protein that is one part (the beta subunit) of a protein complex called cGMP-PDE. This complex is found in specialized light receptor cells called rods.

目的了解常染色体隐性遗传视网膜色素变性(autosomal recessive retinitis pigmentosa,ARRP)致病基因磷酸二酯酶β亚单位(phosphodiesterase β subunit,PDE6B)基因在中国视网膜色素变性(retinitis pigmentosa, RP)患者中的突变谱及突变率.方法应用聚合酶链反应-单链构象多态性,对收集的35个 ...

光子吸收触发杆状光感受器中的信号级联，激活 cGMP 磷酸二酯酶 (PDE) ，导致 cGMP 快速水解、cGMP 门控阳离子通道关闭和细胞超极化。 PDE 是由 α、β 和 γ 亚基组成的外周膜异源三聚体酶。 该基因编码β亚基。 该基因的突变导致色素性视网膜炎和常染色体显性先天性静止性夜盲症。 已发现该基因编码不同异构体的多个转录变体。 [RefSeq 提供，2009 年 2 月]

PDE6, also known as the photoreceptor phosphodiesterases, contains three genes, PDE6A (chromosomes 5q31.2–34), PDE6B (chromosomes 4p16.3), and PDE6C (chromosomes 10q24).

In this retrospective, longitudinal, observational cohort study, we investigated the phenotypic and genotypic features of retinitis pigmentosa associated with variants in the PDE6B gene. Patients underwent clinical examination and genetic testing at ...

Feb 8, 2025 · Photon absorption triggers a signaling cascade in rod photoreceptors that activates cGMP phosphodiesterase (PDE), resulting in the rapid hydrolysis of cGMP, closure of cGMP-gated cation channels, and hyperpolarization of the cell. PDE is a peripheral membrane heterotrimeric enzyme made up of alpha, beta, and gamma subunits.

Clinical and genetic characterization of a Chinese family with PDE6B is reported. Photon absorption triggers a signaling cascade in rod photoreceptors that activates cGMP phosphodiesterase (PDE), resulting in the rapid hydrolysis of cGMP, closure of cGMP-gated cation channels, and hyperpolarization of the cell.
