pfam09728: Taxilin (this model, PSSM-Id:401609 is obsolete and has been replaced by 462861)
Myosin-like coiled-coil protein
Taxilin contains an extraordinarily long coiled-coil domain in its C-terminal half and is ubiquitously expressed. It is a novel binding partner of several syntaxin family members and is possibly involved in Ca2+-dependent exocytosis in neuroendocrine cells. Gamma-taxilin, described as leucine zipper protein Factor Inhibiting ATF4-mediated Transcription (FIAT), localizes to the nucleus in osteoblasts and dimerizes with ATF4 to form inactive dimers, thus inhibiting ATF4-mediated transcription.
