emb-1 Encodes the APC16 Subunit of the Caenorhabditis elegans Anaphase-Promoting Complex
In the nematode Caenorhabditis elegans, temperature-sensitive mutants of emb-1 arrest as one-cell embryos in metaphase of meiosis I in a manner that is indistinguishable from embryos that have been depleted of known subunits of the anaphase-promoting complex or cyclosome (APC/C). Here we show that the emb-1 phenotype is enhanced in double mutant combinations with known APC/C subunits and suppre...
متن کاملEmb(m, N)
Aim of this note is to gain cohomological information about the manifold Emb(M, N) from the topology of the target manifold N . For special conditions, a monomorphism H(N)→ H(Emb(M,N)) is constructed. Let Embg(M,N) be the manifold of all embeddings of a manifold M into a manifold N that differ from a fixed reference embedding g only within a compact subset of M . Note that if M is compact then ...
متن کاملemb-4 is a conserved gene required for efficient germline-specific chromatin remodeling during Caenorhabditis elegans embryogenesis.
In C. elegans, germline blastomeres are initially kept transcriptionally quiescent by the maternally loaded CCCH zinc-finger protein PIE-1. PIE-1 disappears upon the birth of the primordial germ cells Z2 and Z3, yet these cells appear to remain quiescent. We have previously demonstrated that there is a chromatin-based repression that succeeds PIE-1 degradation. The chromatin in Z2/Z3 loses cert...
متن کاملEMB-4: a predicted ATPase that facilitates lin-12 activity in Caenorhabditis elegans.
The sel-6 gene was previously identified in a screen for suppressors of the egg-laying defect associated with hypermorphic alleles of lin-12 (Tax et al. 1997). Here we show that sel-6 and two other previously defined genes, mal-2 and emb-4, are the same gene, now called "emb-4." We perform a genetic and molecular characterization of emb-4 and show that it functions cell autonomously as a positi...
متن کاملAutophagy genes unc-51 and bec-1 are required for normal cell size in Caenorhabditis elegans.
Here we show that in the nematode Caenorhabditis elegans mutational inactivation of two autophagy genes unc-51/atg1 and bec-1/atg6/beclin1 results in small body size without affecting cell number. Furthermore, loss-of-function mutations in unc-51 and bec-1 suppress the giant phenotype of mutant animals with aberrant insulin-like growth factor-1 (insulin/IGF-1) or transforming growth factor-beta...
