Periphilin 1 Rabbit Polyclonal Antibody

The protein encoded by this gene is one of the several proteins that become sequentially incorporated into the cornified cell envelope during the terminal differentiation of keratinocyte at the outer layers of epidermis. This protein interacts with periplakin, which is known as a precursor of the cornified cell envelope. The cellular localization pattern and insolubility of this protein suggest that it may play a role in epithelial differentiation and contribute to epidermal integrity and barrier formation. Multiple alternatively spliced transcript variants encoding distinct isoforms have been observed. [provided by RefSeq, Jul 2008], function:Involved in epithelial differentiation and contributes to epidermal integrity and barrier formation., PTM:Substrate of transglutaminase (in vitro) ., subcellular location:In undifferentiated keratinocytes expressed in speckle-type nuclear granules and at the nuclear membrane, but in the differentiated keratinocytes colocalized with periplakin at the cell periphery and at cell-cell junctions., subunit:Homodimer. Interacts with PPL., tissue specificity:Ubiquitous.
