**Background of Recombinant Human PKD2L1 Protein**
Recombinant human PKD2L1 (Polycystic Kidney Disease 2-Like 1) protein is a calcium-permeable ion channel belonging to the transient receptor potential (TRP) superfamily. It is encoded by the *PKD2L1* gene and structurally classified as a member of the TRPP (polycystin) subfamily. PKD2L1 forms heteromeric complexes with other polycystin proteins, such as PKD1L3. to function as a non-selective cation channel activated by pH changes, particularly in acidic environments.
Biologically, PKD2L1 is implicated in sensory signaling pathways. It is expressed in specialized cells, including taste receptor cells involved in sour taste perception and neurons in the central nervous system (CNS). In the CNS, PKD2L1 is enriched in hypothalamic neurons and cerebrospinal fluid (CSF)-contacting cells, where it may regulate physiological responses to extracellular pH fluctuations, such as chemosensation and respiratory control.
Recombinant PKD2L1 is typically produced in mammalian expression systems (e.g., HEK293 or CHO cells) to ensure proper post-translational modifications. Its study aids in elucidating ion channel mechanics, pH-dependent signaling, and roles in diseases like neurodegenerative disorders or acid-sensing deficits. Additionally, it serves as a tool for drug screening targeting TRPP channels. Research on PKD2L1 continues to uncover its diverse functions in cellular homeostasis and sensory biology.
