Cellular Stress Response

admin — Wed, 26 Aug 2026 22:19:52 +0000

Cellular stress responses are adaptive defence mechanisms that protect cells from environmental, metabolic and proteotoxic stress. By activating heat‑shock proteins, unfolded protein responses, antioxidant pathways and autophagy, cells restore homeostasis and maintain functional integrity under adverse conditions.

RBR Ubiquitin Ligase

admin — Fri, 21 Aug 2026 09:25:22 +0000

RBR ubiquitin ligases are hybrid E3 enzymes that combine RING‑type E2 binding with HECT‑like catalytic ubiquitin transfer. Through key members such as Parkin, HHARI and HOIP, the RBR family regulates mitophagy, protein‑quality control and M1‑linked ubiquitination in immune signalling, making them central to cellular stress responses and disease mechanisms.
