General annotation (Comments)

Function

This is a receptor for the anterior pituitary hormone prolactin (PRL). Isoforms 4 and 6 are unable to transduce prolactin signaling. Ref.6

Subunit structure

Interacts with SMARCA1. Interacts with GH1. Ref.4 Ref.9

Subcellular location

Membrane; Single-pass type I membrane protein. Secreted. Note: Isoform 7. Ref.6 Ref.4

Tissue specificity

Expressed in breast, placenta, kidney, liver and pancreas. Ref.6 Ref.4

Domain

The WSXWS motif appears to be necessary for proper protein folding and thereby efficient intracellular transport and cell-surface receptor binding.

The box 1 motif is required for JAK interaction and/or activation.

Sequence similarities

Belongs to the type I cytokine receptor family. Type 1 subfamily.

Contains 2 fibronectin type-III domains.

Alternative products

This entry describes 8 isoforms produced by alternative splicing. [Align] [Select]
Isoform 1 (identifier: P16471-1)

The sequence of this isoform differs from the canonical sequence as follows:
     24-124: Missing.

     377-622: Missing.
Note: Includes exon 11. Does not transduce prolactin signaling.
Isoform 5 (identifier: P16471-5)

The sequence of this isoform differs from the canonical sequence as follows:
     337-349: GMKPTYLDPDTDS → EREQRQAQEARDS
     350-622: Missing.
Note: Produced by deletion of part of exon 10 and frameshift.
Isoform 6 (identifier: P16471-6)

Also known as: SF1b; Short form 1b;

The sequence of this isoform differs from the canonical sequence as follows:
     286-288: KGK → VTP
     289-622: Missing.
Note: Does not transduce prolactin signaling.
Isoform 7 (identifier: P16471-7)

Also known as: Delta 7/11;

The sequence of this isoform differs from the canonical sequence as follows:
     229-268: DFTMNDTTVW...KGYSMVTCIF → GDPLMLGASH...FTKATLTTVQ
     269-622: Missing.
Note: Splices from exon 7 to exon 11. Secreted.
Isoform 8 (identifier: P16471-8)

Also known as: Delta 4-SF1b;

The sequence of this isoform differs from the canonical sequence as follows:
     1-71: Missing.
     286-288: KGK → VTP
     289-622: Missing.
Note: SF1b with deletion of exon 4.
