Summary: Predicted to enable cytoskeletal anchor activity and protein domain specific binding activity. Predicted to be involved in several processes, including apical protein localization; establishment of mitotic spindle orientation; and regulation of asymmetric cell division. Predicted to be located in plasma membrane. Predicted to be part of protein-containing complex. Predicted to be active in apical cortex. Predicted to colocalize with cell cortex. Is expressed in bone; lung epithelium; metanephros; and nervous system. Orthologous to human INSC (INSC spindle orientation adaptor protein). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

Excess mINSC drives symmetric cell division, more stem cells and enhanced mammary outgrowth.
Title: Mammary Stem Cell Self-Renewal Is Regulated by Slit2/Robo1 Signaling through SNAI1 and mINSC.
Data (including data from studies using embryonic stem cell line) suggest that expression of Insc (inscuteable cell cycle protein) is up-regulated by c-Rel in cell differentiation; minimum transcriptional regulatory element (354 bases) was identified.
Title: c-Rel Regulates Inscuteable Gene Expression during Mouse Embryonic Stem Cell Differentiation.
support for the hitherto untested model that Par3-mInsc and Galphai3 act cooperatively to polarize LGN and promote perpendicular divisions
Title: Par3-mInsc and Gαi3 cooperate to promote oriented epidermal cell divisions through LGN.
Insc controls directional migration via noncanonical G protein signaling, in which Gbetagamma-free Galphai-GDP, a product from Galphai-GTP released after receptor activation, plays a central role.
Title: The cell polarity protein mInsc regulates neutrophil chemotaxis via a noncanonical G protein signaling pathway.
Mouse inscuteable induces apical-basal spindle orientation, which affects the rate of indirect neurogenesis, a process where progenitors give rise to basal progenitors, which in turn divide symmetrically into two differentiating neurons.
Title: Mouse inscuteable induces apical-basal spindle orientation to facilitate intermediate progenitor generation in the developing neocortex.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
