Insulin-Like Peptide 4 (INSL4) — frequently asked

What is INSL4?
INSL4, also called early placenta insulin-like peptide, belongs to the insulin/relaxin superfamily. Its expression is reported to be largely restricted to placental tissue, and it is studied mainly through its precursor rather than a defined mature hormone.
Why is the C-peptide region used for assays?
The connecting C domain is distinct from equivalent regions in other superfamily members and is relatively straightforward to synthesise. That makes it a practical antigen for raising selective antibodies and for building immunoassays that avoid cross-reactivity.
Does INSL4 have a known receptor?
No receptor is widely accepted for INSL4, unlike relaxin family members that act at RXFP receptors. Available literature focuses largely on expression, processing and detection, so functional claims should be treated as provisional.
