General annotation (Comments)
| Function | Regulatory subunit of the condensin-2 complex, a complex that seems to provide chromosomes with an additional level of organization and rigidity and in establishing mitotic chromosome architecture. May play a role in lineage-specific role in T-cell development By similarity. Ref.6 |
| Subunit structure | Component of the condensin-2 complex, which contains the SMC2 and SMC4 heterodimer, and three non SMC subunits, NCAPG2, NCAPH2 and NCAPD3 that probably regulate the complex. Ref.6 |
| Subcellular location | Nucleus. Chromosome. Note: Distributed along the arms of chromosomes assembled in vivo and in vitro. Ref.6 |
| Sequence similarities | Belongs to the CND2 H2 (condensin-2 subunit 2) family. |
| Sequence caution | The sequence AAB03345.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence AAH00473.1 differs from that shown. Reason: Erroneous initiation. The sequence AAH01509.1 differs from that shown. Reason: Erroneous initiation. The sequence AAH01833.1 differs from that shown. Reason: Erroneous initiation. The sequence AAH01937.1 differs from that shown. Reason: Erroneous initiation. The sequence AAH09441.1 differs from that shown. Reason: Erroneous initiation. The sequence CAA16670.1 differs from that shown. Reason: Frameshift at positions 56 and 429. The sequence EAW73552.1 differs from that shown. Reason: Erroneous gene model prediction. |
