Here are recombinant proteins for H1FOO, the approved symbol for the human gene, 'H1 histone family member O oocyte specific'. With a Uniprot ID of Q8IZA3, this protein is listed as having 346 residues in length and a mass of 35.9 kDa. Up to 2 isoforms are reported. The following protein function has been assigned: 'May play a key role in the control of gene expression during oogenesis and early embryogenesis, presumably through the perturbation of chromatin structure.' A subcellular localization as 'cytoplasmic, nuclear' is noted. Orthologs are reported in these species: mouse, rat. H1FOO may also be known by other designations: 'histone H1oo, oocyte-specific histone H1, oocyte-specific linker histone H1'.
