Predicted to enable DNA binding activity. Involved in larval somatic muscle development. Located in nucleus and polytene chromosome band. Orthologous to several human genes including H2AC11 (H2A clustered histone 11); H2AC12 (H2A clustered histone 12); and H2AC13 (H2A clustered histone 13).
The gene His2A:CG33820 is referred to in FlyBase by the symbol Dmel\His2A:CG33820 (CG33820, FBgn0053820). It is a protein_coding_gene from Dmel. It has one annotated transcript and one polypeptide. Gene sequence location is 2L:21463055..21463547. Its molecular function is described by: structural constituent of chromatin; protein heterodimerization activity; DNA binding. It is involved in the biological process described with: chromatin organization; larval somatic muscle development; heterochromatin formation; nucleosome assembly. No alleles are reported. Summary of modENCODE Temporal Expression Profile: No expression detected at any stage of development. CAVEAT: These RNA-Seq temporal profiles depend upon RNA-Seq reads that are uniquely placed in the genome. For this reason, genes such as histones, Stellates and many classes of RNA genes that are present in multiple exact or near exact copies in the genome, expression levels may be reported as much lower than their true values.

AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.

There is only one protein coding transcript and one polypeptide associated with this gene
The nucleosome is a histone octamer containing two molecules each of H2A, H2B, H3 and H4 assembled in one H3-H4 heterotetramer and two H2A-H2B heterodimers. The octamer wraps approximately 147 bp of DNA.
The chromatin-associated form, but not the free cytoplasmic form, is phosphorylated on Thr-120 by NHK-1 during mitosis, and dephosphorylated during S-phase. Also phosphorylated on Thr-120 by NHK-1 during prophase I of meiosis; which is required for acetylation of H3 'Lys-14' and H4 'Lys-5', diassembly of the synaptonemal complex, and karyosome formation.
Monoubiquitination of Lys-119 by sce/dRING gives a specific tag for epigenetic transcriptional repression (PubMed:15386022). Deubiquitinated by the polycomb repressive deubiquitinase (PR-DUB) complex (PubMed:20436459, PubMed:30258054, PubMed:30639226).
Phosphorylation on Ser-2 is enhanced during mitosis. Phosphorylation on Ser-2 directly represses transcription (By similarity).

The testis specificity index was calculated from modENCODE tissue expression data by Vedelek et al., 2018 to indicate the degree of testis enrichment compared to other tissues. Scores range from -2.52 (underrepresented) to 5.2 (very high testis bias).

Please Note This section lists cDNAs and ESTs that fall within the genomic extent of the gene model, which may include cDNAs and ESTs of genes within introns, or of overlapping genes. Please see JBrowse for alignment of the cDNAs and ESTs to the gene model.
For each fully sequenced cDNA the DGRC maintains various forms of the cDNA (e.g tagged or untagged) in several different host vectors for subsequent cloning and expression in Drosophila and Drosophila cell lines.
