Last Modified 2014-10-13 [Report errors or provide feedback]
Gene Symbol Sprr1b
Protein Name small proline-rich protein 1B
Synonyms
Species Mus musculus
Ensembl Protein ENSMUSP00000058617
InnateDB Gene IDBG-168618 (Sprr1b)
Protein Structure
UniProt Annotation
Function Cross-linked envelope protein of keratinocytes. It is a keratinocyte protein that first appears in the cell cytosol, but ultimately becomes cross-linked to membrane proteins by transglutaminase. All that results in the formation of an insoluble envelope beneath the plasma membrane.
Subcellular Localization Cytoplasm.
Disease Associations
Tissue Specificity Expressed in fetal periderm, hair follicles and in the thickened epidermis of the lip and footpad. Also present in the epithelia of various tissues such as the penis, vagina, forestomach, tongue and esophagus.
