Abstract

For over a decade, p130Cas/BCAR1, HEF1/NEDD9/Cas-L, and Efs/Sin have defined the Cas (Crk-associated substrate) scaffolding protein family. Cas proteins mediate integrin-dependent signals at focal adhesions, regulating cell invasion and survival; at least one family member, HEF1, regulates mitosis. We here report a previously undescribed novel branch of the Cas protein family, designated HEPL (for HEF1-Efs-p130Cas-like). The HEPL branch is evolutionarily conserved through jawed vertebrates, and HEPL is found in some species lacking other members of the Cas family. The human HEPL mRNA and protein are selectively expressed in specific primary tissues and cancer cell lines, and HEPL maintains Cas family function in localization to focal adhesions, as well as regulation of FAK activity, focal adhesion integrity, and cell spreading. It has recently been demonstrated that upregulation of HEF1 expression marks and induces metastasis, whereas high endogenous levels of p130Cas are associated with poor prognosis in breast cancer, emphasizing the clinical relevance of Cas proteins. Better understanding of the complete protein family should help inform prediction of cancer incidence and prognosis.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Cas proteins are critically involved in the regulation of focal adhesions.

    “Cas proteins are best known for their critical involvement in the regulation of focal adhesions (Deneka et al., 2015; Singh et al., 2008)”
  • CASS4 is a member of the Cas protein family.

    “These studies have helped to identify CASS4 as a member of the Cas protein family (Singh et al., 2008).”

    From Alzheimer’s genetic risk factor CASS4 controls microglial focal adhesion biology and amyloidosis (2026) · cites this paper as Singh et al., 2008

    The Results section identifies HEPL as a new Cas family member, but the passages from our copy do not identify HEPL as CASS4. A search for “CASS4” found no passage establishing that link, so this copy alone cannot verify the claim about CASS4. (LLM, conf=0.72)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
