The CIP2A-TOPBP1 complex safeguards chromosomal stability during mitosis

Nature Communications, 2022
In this work, CIP2A is discovered as a TOPBP1-interacting protein that regulates TOPBP1 localization specifically in mitosis. Cells lacking CIP2A display increased radio-sensitivity, micronuclei formation and chromosomal instability.

CIP2A promotes proliferation of spermatogonial progenitor cells and spermatogenesis in mice.

PLoS ONE, 2012
Protein phosphatase 2A (PP2A) is a critical regulator of protein serine/threonine phosphorylation. However, the physiological and developmental roles of different PP2A complexes are very poorly understood.

Estrogen Receptor Beta Isoforms Interplay Integrates Nuclear and Extra‐Nuclear Signaling to Modulate Human Granulosa Cell Growth

The FASEB Journal, Volume 40, Issue 19, 15 October 2026.
Working model of ERβ isoform signaling in human granulosa cells. Upon E2 binding, ERβ1 activates ERE‐dependent transcription and represses AP‐1 activity through Jun/Fos interactions. In contrast, ERβ2, ERβ4, and ERβ5 lack E2 binding and ERE activity but promote AP‐1‐dependent transcription and counteract ERβ1 repression, including after phosphorylation

Prognostic significance of CIP2A expression in solid tumors: A meta-analysis. [PDF]

PLoS ONE, 2018
CIP2A, cancerous inhibitor of protein phosphatase 2A, was initially recognized as an oncoprotein. Recently several studies revealed that CIP2A could function as a prognosis biomarker, however, the result remained not comprehensive, partly due to small ...

Microprotein MP104 Promotes Malignant Progression of Colorectal Cancer Through Regulating Protein Translation

Advanced Science, Volume 13, Issue 56, 9 October 2026.
A previously unrecognized microprotein, MP104, encoded by ZEB1‐AS1, emerges as a critical driver of colorectal cancer progression. MP104 links ubiquitin‐mediated protein degradation with translational reprogramming via the UBE2O–AMPKα2–mTOR–EIF4B axis, revealing an unrecognized layer of oncogenic regulation.

CIP2A mediates mitotic recruitment of SLX4/MUS81/XPF to resolve replication stress-induced DNA lesions

Nature Communications
Perturbed DNA replication can lead to incompletely replicated DNA when cells enter mitosis and can interfere with chromosome segregation. Cells therefore require mechanisms to resolve these lesions during mitosis. The CIP2A-TOPBP1 complex is described to

Corynoxine Inhibits Tumor Growth via Targeting NQO1 and Modulating the PTPA–NQO1/PP2A Switch to Activate PP2A

Advanced Science, Volume 13, Issue 60, 28 October 2026.
Corynoxine exerts potent broad‐spectrum anticancer activity by directly targeting NQO1. This interaction dissociates the oncogenic NQO1‐PTPA complex, releasing PTPA to robustly activate the tumor suppressor PP2A. Consequently, downstream Raf/MEK/ERK and PI3K/AKT signaling pathways are suppressed, downregulating c‐Myc and driving tumor regression ...

An Integrated Proteomics and Genomics Approach to Identify Essential Protein Kinases During Human Trophoblast Development

The FASEB Journal, Volume 40, Issue 17, 15 September 2026.
Integrated quantitative proteomic, phosphoproteomic, and transcriptomic analyses of human trophoblast stem cells identify stage‐specific kinase signaling networks that regulate trophoblast self‐renewal and differentiation into syncytiotrophoblasts and extravillous trophoblasts.
