The Cleavage Furrow (contractile ring) and Cytokinesis ... The cleavage furrow is an actin rich "purse string" that draws tight to separate daughter cells to complete cytokinesis in cell division. Early work established that the contractile ring was composed of filaments (Schroeder, 1968), which were later identified as...

Ring contraction is associated with centripetal growth of the membrane that deepens the cleavage furrow and divides the cytoplasm of the two daughter cells. While the term 'cleavage furrow' was initially associated with animal cells, such a structure occurs in many other types of cells, including unicellular protists.

Confocal microscopy analysis of endogenous PSTPIP revealed colocalization with the cortical actin cytoskeleton, lamellipodia, and actin-rich cytokinetic cleavage furrow. Overexpression of PSTPIP in 3T3 cells resulted in the formation of extended filopodia, consistent with a role for this protein in actin reorganization.

Using site- and phosphorylation state-specific antibodies (Inagaki et al., 1997a), we previously detected cleavage furrow kinase (CF kinase) activity that phosphorylates Thr7, Ser13 and Ser38 on human glial fibrillary acidic protein (GFAP) at the cleavage furrow during cytokinesis (Matsuoka et al., 1992).

We have previously reported that Rho-kinase accumulates at the cleavage furrow during cytokinesis in several cultured cells. ... We have previously reported that Rho-kinase also accumulates at the cleavage furrow during cytokinesis (Kosako et al., 1999). Furthermore, a dominant negative form of Rho-kinase was reported...

We reported that microinjection of Ca2+ store-enriched microsome fractions from cultured CHO cells and mouse cerebella to dividing newt eggs induced extra-cleavage furrows via inositol 1,4,5-trisphosphate-induced Ca2+ release (Mitsuyama et al. ... Cleavage Stage, Ovum [physiology]
