Recombinant Human Holliday junction recognition protein (HJURP)

Q8NCD3

Target Species

Human

Target Name

HJURP

Target Full Name

Holliday junction recognition protein

Target Function

Centromeric protein that plays a central role in the incorporation and maintenance of histone H3-like variant CENPA at centromeres. Acts as a specific chaperone for CENPA and is required for the incorporation of newly synthesized CENPA molecules into nucleosomes at replicated centromeres. Prevents CENPA-H4 tetramerization and prevents premature DNA binding by the CENPA-H4 tetramer. Directly binds Holliday junctions.

Target Subcellular Location

Nucleus, nucleolus. Chromosome, centromere. Note=Localizes in centromeres during late telophase and early G1, when CENPA nucleosomes are assembled. Localizes to nucleolus during S phase, nucleolus site being often related to storage.

Target Tissue Specificity

According to PubMed:17256767, highly expressed in the thymus with lower levels in the placenta, small intestine, liver, skeletal muscle, and colon. According to PubMed:17823411, highly expressed in testis, and at a relatively lower level in thymus and bon

Target Background

Enables histone binding activity and identical protein binding activity. Involved in several processes, including CENP-A containing chromatin assembly; regulation of DNA binding activity; and regulation of protein-containing complex assembly. Located in kinetochore; mitochondrion; and nuclear lumen.
