A family of rat CRMP genes is differentially expressed in the nervous system.

ABSTRACT: Members of the collapsin/semaphorin family play an important role in creating the complex pattern of neuronal connectivity. Inhibition of growth cone motility by chick collapsin is mediated by the intraneuronal protein CRMP-62. We have now isolated four rat sequences that are highly related to chick CRMP-62. All four genes are expressed exclusively in the nervous system and primarily during development. Rat CRMP-2/TOAD-64 is most closely related to chick CRMP-62 and is the most widely expressed CRMP within the nervous system. Rat CRMP-1 and CRMP-4/rUlip are expressed during discrete periods of neuronal development and are not found in the adult nervous system. Rat CRMP-3 has a distinct distribution, being expressed transiently in developing spinal cord and selectively in the postnatal cere
