General Information
Term histone locus body ID (Ontology) GO:0035363 (Gene Ontology)
Definition A nuclear body associated with the histone gene locus that is thought to contain all of the factors necessary for histone mRNA transcription and pre-mRNA processing. In Drosophila, U7 snRNP is located in the histone locus body rather than the distinct Cajal body.[ PubMed:16533947 PubMed:18927579 PubMed:19620235 ]
