Previous GeneCards Identifiers for H3F3C Gene
Histones are basic nuclear proteins that are responsible for the nucleosome structure of the chromosomal fiber in eukaryotes. Nucleosomes consist of approximately 146 bp of DNA wrapped around a histone octamer composed of pairs of each of the four core histones (H2A, H2B, H3, and H4). The chromatin fiber is further compacted through the interaction of a linker histone, H1, with the DNA between the nucleosomes to form higher order chromatin structures. This gene contains introns and its mRNA is polyadenylated, unlike most histone genes. The protein encoded by this gene is a replication-independent histone that is a member of the histone H3 family.

GeneCards Summary for H3F3C Gene
H3F3C (H3 Histone, Family 3C) is a Protein Coding gene. Among its related pathways are Transcriptional misregulation in cancer and RNA Polymerase I Promoter Opening. GO annotations related to this gene include protein heterodimerization activity and nucleosomal DNA binding. An important paralog of this gene is HIST2H3A.
UniProtKB/Swiss-Prot for H3F3C Gene
Core component of nucleosome. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post-translational modifications of histones, also called histone code, and nucleosome remodeling. Hominid-specific H3.5/H3F3C preferentially colocalizes with euchromatin, and it is associated with actively transcribed genes.
