Summary: This gene encodes a receptor for the anterior pituitary hormone, prolactin, and belongs to the type I cytokine receptor family. Prolactin-dependent signaling occurs as the result of ligand-induced dimerization of the prolactin receptor. Several alternatively spliced transcript variants encoding different membrane-bound and soluble isoforms have been described for this gene, which may function to modulate the endocrine and autocrine effects of prolactin in normal tissue and cancer.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

Status: REVIEWED

Description

Transcript Variant: This variant (6) lacks two in-frame coding exons compared to variant 1. This results in a shorter isoform (6, also known as deltaS1) missing an internal protein segment coding for the S1 motif, compared to isoform 1. This isoform has been shown to be expressed at the protein level on the cell surface, and is functional (PMID:12351696).

Status: REVIEWED

Description

Transcript Variant: This variant (2) is alternatively spliced at the 3' end compared to variant 1. This results in a frame-shift and a shorter isoform (2, also known as intermediate form) with a distinct C-terminus compared to isoform 1. This isoform is functional, but has different tissue specific expression and signaling pattern from isoform 1 (PMID:10585417).

Transcript Variant: This variant (3) contains an alternate 3' terminal exon compared to variant 1. This results in a frame-shift and a shorter isoform (3, also known as SF1a for short form 1a) with a distinct C-terminus compared to isoform 1. This isoform is functional with a dominant-negative effect on the function of isoform 1 (PMID:12580759).

NR_037910.1 RNA Sequence

Status: REVIEWED

Description

Transcript Variant: This variant (7) lacks two non-consecutive exons, and contains an alternate 3' terminal exon compared to variant 1. This variant is represented as non-coding because the use of the 5'-most supported translational start codon, as used in variant 1, renders this transcript a candidate for nonsense-mediated mRNA decay (NMD).
