Recombinant Human Liprin-alpha-1 (PPFIA1), Truncated

Uniprot Id

Q13136

Target Species

Human

Target Name

PPFIA1

Target Full Name

Liprin-alpha-1

Target Function

May regulate the disassembly of focal adhesions. May localize receptor-like tyrosine phosphatases type 2A at specific sites on the plasma membrane, possibly regulating their interaction with the extracellular environment and their association with substrates.

Target Subcellular Location

Cytoplasm. Note=Colocalizes with PTPRF at the ends of focal adhesions most proximal to the cell nucleus.

Target Protein Families

Liprin family, Liprin-alpha subfamily

Target Tissue Specificity

Ubiquitous.

Target Synonyms

Target Background

The protein encoded by this gene is a member of the LAR protein-tyrosine phosphatase-interacting protein (liprin) family. Liprins interact with members of LAR family of transmembrane protein tyrosine phosphatases, which are known to be important for axon guidance and mammary gland development. This protein binds to the intracellular membrane-distal phosphatase domain of tyrosine phosphatase LAR, and appears to localize LAR to cell focal adhesions. This interaction may regulate the disassembly of focal adhesion and thus help orchestrate cell-matrix interactions. Alternatively spliced transcript variants encoding distinct isoforms have been described.
