Source

Human Prolactin R Protein, His Tag&Tag Free (PRR-H52H3) is expressed from human 293 cells (HEK293). It contains AA Gln 25 - Asp 234 (Accession # P16471-1).

Predicted N-terminus: Gln 25

Molecular Characterization

The protein has a calculated MW of 31.1 kDa. The protein migrates as 33-36 kDa and 38-41 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

The protein is designed as a dimer.

Endotoxin

Less than 0.01 EU per μg by the LAL method / rFC method.

Purity

>95% as determined by SDS-PAGE.

>90% as determined by SEC-MALS.

Formulation

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

Background

The prolactin receptor (PRLR) is a transmembrane protein belonging to the class I cytokine receptor superfamily, widely expressed in mammary gland, reproductive organs, liver, and brain. Signal activation is initiated when a single prolactin (PRL) molecule binds to this pre-dimerized PRLR, inducing a specific conformational change. This triggers the associated JAK2 kinases to phosphorylate each other and the receptor, ultimately leading to the recruitment and activation of downstream STAT5 transcription factors. This precise mechanism governs essential physiological processes, including lactation, reproduction, metabolism, and immune function, and its dysregulation is implicated in diseases such as certain cancers and endometriosis.
