You will be shown biomedical passages and your task is to the answer the provided question. Provide a concise and accurate response and do not include any additional text in the response other than the answer.

Question: Which is the substrate of the haspin kinase during mitosis?

Context: aspin phosphorylates histone H3 at Thr3 (H3T3ph) during mitosis
protein kinase Haspin-mediated spreading of H3T3ph
Haspin localizes predominantly to chromosomes and phosphorylates histone H3 at threonine-3 during mitosis
haspin/Gsg2 plays an important role in mitosis, where it specifically phosphorylates Thr-3 in histone H3 (H3T3
aspin/Gsg2 is a kinase that phosphorylates histone H3 at Thr-3 (H3T3ph) during mitosis.
H3T3 phosphorylation is catalyzed by Haspin
aspin is an atypical protein kinase that in several organisms phosphorylates histone H3Thr3
histone H3 that is phosphorylated at T3 (H3T3ph) by Aurora B-stimulated Haspin.
phosphorylating Thr3 of histone H3, Haspin promotes centromeric recruitment of the chromosome passenger complex (CPC) during mitosis.
aspin phosphorylates histone H3 at threonine-3 (H3T3ph),
Haspin-dependent histone H3 phosphorylatio
aspin is a serine/threonine kinase that phosphorylates Thr-3 of histone H3 in mitosis
Haspin is a protein kinase the only known target of which is phosphorylation of histone H3 at Thr3 residue (H3T3ph)
Haspin in vitro phosphorylates histone H3 at threonine 3
Haspin is a histone H3 Thr3 kinase that has important roles in chromosome cohesion during mitosis
phosphorylation of histone H3 threonine 3 (H3-pT3) mediated by Haspin
histone H3 specifically when it is phosphorylated at threonine 3, a mark that is placed by the mitotic kinase, haspin
H3T3 kinase haspin
phosphorylation of histone H3-threonine 3 (H3-pT3) mediated by Haspin
kinase activity of Haspin, which phosphorylates H3T3,
istone H3 Thr-3 phosphorylation by Haspin
phosphorylation of histone H3 threonine 3 (H3T3ph) by Haspin
Haspin/Gsg2 is a histone H3 threonine-3 kinase
During mitosis haspin is phosphorylated, associates with the chromosomes, centrosomes and spindle, and is responsible for phosphorylation of histone H3 at threonine-3
haspin, a member of a distinctive group of protein kinases present in diverse eukaryotes, phosphorylates H3 at Thr 3
Haspin phosphorylated histone H3 at both Thr3 and Thr11 in vitro.
Haspin kinase is a histone H3 threonine kinase
Haspin phosphorylated histone H3 at both Thr3 and Thr11 in vitro
Histone 3 at Thr3
