Histone H2A type 1 is a protein that in humans is encoded by the HIST1H2AI gene.{{cite journal |vauthors=Albig W, Doenecke D | title = The human histone gene cluster at the D6S105 locus | journal = Hum Genet | volume = 101 | issue = 3 | pages = 284–94 |date=Feb 1998 | pmid = 9439656 | doi =10.1007/s004390050630 | s2cid = 38539096 }}{{cite journal |vauthors=Marzluff WF, Gongidi P, Woods KR, Jin J, Maltais LJ | title = The human and mouse replication-dependent histone genes | journal = Genomics | volume = 80 | issue = 5 | pages = 487–98 |date=Oct 2002 | pmid = 12408966 | doi =10.1016/S0888-7543(02)96850-3 }}{{cite web | title = Entrez Gene: HIST1H2AI histone cluster 1, H2ai| url = https://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=8329}}

Histones are basic nuclear proteins that are responsible for the nucleosome structure of the chromosomal fiber in eukaryotes. Two molecules of each of the four core histones (H2A, H2B, H3, and H4) form an octamer, around which approximately 146 bp of DNA is wrapped in repeating units, called nucleosomes. The linker histone, H1, interacts with linker DNA between nucleosomes and functions in the compaction of chromatin into higher order structures. This gene is intronless and encodes a member of the histone H2A family. Transcripts from this gene lack polyA tails but instead contain a palindromic termination element. This gene is found in the small histone gene cluster on chromosome 6p22-p21.3.
