What pLDDT means and how to read it

Function

Promotes guanine-nucleotide exchange on ARF1 and ARF6. Promotes the activation of ARF factors through replacement of GDP with GTP. Plays a role in the epithelial polarization (By similarity)

Subunit structure

Interacts with TAMALIN (By similarity). Interacts with ARF6 (PubMed:23940353). Interacts with FRMD4A (By similarity). Interacts with FRMD4B (By similarity)

Subcellular location

Cytoplasm, cytosol, Cell membrane, Cell junction, adherens junction, Cell junction, tight junction
