**Background of INSRR Recombinant Protein**
The insulin receptor-related receptor (INSRR) is a member of the receptor tyrosine kinase (RTK) family, closely related to the insulin receptor (INSR) and insulin-like growth factor-1 receptor (IGF-1R). Primarily expressed in kidney, nervous system, and reproductive tissues, INSRR is unique for its pH-sensitive activation mechanism. Unlike INSR or IGF-1R, which respond to insulin or growth factors, INSRR is activated under alkaline conditions (pH >7.9), suggesting a potential role in systemic pH homeostasis and metabolic regulation.
Structurally, INSRR consists of extracellular ligand-binding domains, a transmembrane region, and intracellular tyrosine kinase domains. Its recombinant form is typically produced via *in vitro* expression systems (e.g., mammalian or bacterial cells) to study its biochemical properties, signaling pathways, and interactions. Recombinant INSRR proteins enable researchers to explore its activation kinetics, downstream targets (e.g., MAPK/ERK pathways), and physiological relevance in pH sensing.
Studies link INSRR to renal tubular function, blood pressure regulation, and electrolyte balance, with knockout models showing altered responses to metabolic acidosis. Additionally, INSRR may interact with neuroendocrine pathways, though its exact biological roles remain under investigation. Recombinant INSRR serves as a critical tool for elucidating its structure-function relationships, pH-dependent activation mechanisms, and potential therapeutic applications in metabolic or acid-base disorders.
This protein’s unique pH sensitivity and tissue-specific expression make it a compelling target for understanding metabolic adaptations and developing novel treatments for conditions like hypertension or renal dysfunction.
