RT isoform at the nodes of Ranvier in developing and adult mouse central
RT nervous systems.";
RL Mol. Cell. Neurosci. 19:43-57(2002).
CC -!- FUNCTION: Mediates a firm binding of versican V2 to hyaluronic acid.
CC May play a pivotal role in the formation of the hyaluronan-associated
CC matrix in the central nervous system (CNS) which facilitates neuronal
CC conduction and general structural stabilization. Binds to hyaluronic
CC acid. {ECO:0000269|PubMed:11817897}.
CC -!- SUBCELLULAR LOCATION: Secreted, extracellular space, extracellular
CC matrix {ECO:0000269|PubMed:11817897}.
CC -!- TISSUE SPECIFICITY: Brain. Predominantly expressed by neurons.
CC Colocalizes with versican V2 in developing and adult cerebellar white
CC matter and at the nodes of Ranvier. {ECO:0000269|PubMed:11027579,
CC ECO:0000269|PubMed:11817897}.
CC -!- DEVELOPMENTAL STAGE: Expression starts at postnatal day 20 and
CC increases thereafter. {ECO:0000269|PubMed:11817897}.
CC -!- SIMILARITY: Belongs to the HAPLN family. {ECO:0000305}.
