Also known as: CCDC99
Summary: This gene encodes a coiled-coil domain-containing protein that functions in mitotic spindle formation and chromosome segregation. The encoded protein plays a role in coordinating microtubule attachment by promoting recruitment of dynein proteins, and in mitotic checkpoint signaling. [provided by RefSeq, Jul 2016]

SPDL1 knockdown in human CRC cells significantly increased invasion and migration of tumor cells. Lower SPDL1 expression levels are significantly associated with reduced survival in CRC patients. SPDL1 depletion in human CRC cells significantly increases tumor development in xenograft assays. SPDL1 is a human CRC tumor-suppressor genes that acts downstream of MRTFB to regulate CRC growth and survival.
Title: MRTFB suppresses colorectal cancer development through regulating SPDL1 and MCAM.
Using mass spectrometry this study identified CCDC99 as a new target of USP45. The data showed that CCDC99 and USP45 are part of the same complex and that their interaction specifically depends on the catalytic activity of USP45.
Title: USP45 and Spindly are part of the same complex implicated in cell migration.
Farnesylation of Spindly is essential for its localization, & thus for proper localization of dynein & dynactin, to prometaphase kinetochores. Both Spindly and CENP-E farnesylation are required for efficient chromosome congression
Title: Preventing farnesylation of the dynein adaptor Spindly contributes to the mitotic defects caused by farnesyltransferase inhibitors.
hSpindly is farnesylated in vivo and farnesylation is essential for its interaction with the RZZ complex and hence Kinetochore localization.
Title: A novel role of farnesylation in targeting a mitotic checkpoint protein, human Spindly, to kinetochores.
Spindly is not only required for kinetochore localization of dynein but is a functional component of a mechanism that couples dynein-dependent poleward movement of chromosomes to their efficient attachment to microtubules.
Title: Spindly/CCDC99 is required for efficient chromosome congression and mitotic checkpoint regulation.
dynein-mediated removal of Spindly from microtubule-attached kinetochores, rather than poleward transport per se, is the critical reaction in checkpoint silencing
Title: Removal of Spindly from microtubule-attached kinetochores controls spindle checkpoint silencing in human cells.
[hSpindly] Localization of human Spindly (hSpindly) to kinetochores is controlled by the Rod/Zw10/Zwilch (RZZ) complex and Aurora B.

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.
