A number of pharmacologically and electrophysiologically distinct voltage-dependent Ca2+ channels have been identified in mammalian neurons. Two rat brain Ca2+ channel alpha 1 subunits (rbC-I and rbC-II) have been isolated by molecular cloning and shown to be highly related (95%) to the cardiac dihydropyridine-sensitive Ca2+ channel. The rbC-II protein is distinct from rbC-I in that it contains a 3 amino acid insert in the putative cytoplasmic loop between domains II and III and a 28 amino acid substitution corresponding to the third transmembrane segment (S3) of the fourth domain. We show that rbC-I and rbC-II transcripts are generated by alternative splicing and that they are differentially expressed in the rat CNS.

D009865 Oocytes Female germ cells derived from OOGONIA and termed OOCYTES when they enter MEIOSIS. The primary oocytes begin meiosis but are arrested at the diplotene state until OVULATION at PUBERTY to give rise to haploid secondary oocytes or ova (OVUM). Ovocytes,Oocyte,Ovocyte
D001921 Brain The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM. Encephalon
D004274 DNA, Recombinant Biologically active DNA which has been formed by the in vitro joining of segments of DNA from different sources. It includes the recombination joint or edge of a heteroduplex region where two recombining DNA molecules are connected.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA. Animal,Metazoa,Animalia

D014158 Transcription, Genetic The biosynthesis of RNA carried out on a template of DNA. The biosynthesis of DNA from an RNA template is called REVERSE TRANSCRIPTION. Genetic Transcription
D014981 Xenopus An aquatic genus of the family, Pipidae, occurring in Africa and distinguished by having black horny claws on three inner hind toes.
