Since betatrophin is a member of the angiopoietin-like gene family and shares extensive homology with Angptl4 and Angptl3, the name Angptl8 is preferred.
CAPD library - C++ library for rigorous numerics in dynamical systems and homology computation.
For example, recA recombinase, that catalyses the key functions of DNA homology search and strand exchange in the bacterial sexual process of transformation, has orthologs in eukaryotes that perform similar functions in meiotic recombination (see Wikipedia articles RecA, RAD51 and DMC1).
Henri Poincaré's 1895 paper Analysis Situs studied three-and-higher-dimensional manifolds(which he called "varieties"), giving rigorous definitions of homology, homotopy (which had originally been defined in the context of late nineteenth-century knot theory, developed by Maxwell and others), and Betti numbers and raised a question, today known as the Poincaré conjecture, based his new concept of the fundamental group.
The MATH domain, in molecular biology, is a binding domain that was defined originally by a region of homology between otherwise functionally unrelated domains, the intracellular TRAF-C domains of TRAF proteins and a C-terminal region of extracellular meprins A and B.
Furthermore, MLC1 has highest homology with the KCNA1 shaker-related voltage-gated potassium channel (Kv1.1).
Like MYOM1, MYOM2 has a unique N-terminal domain followed by 12 repeat domains with strong homology to either fibronectin type III or immunoglobulin C2 domains.
This kind of cobordism theory is a homology theory whose coefficients have been calculated by Thom: therefore the cobordism classes of such maps are computable at least in theory for all spaces .
A review of Of Pandas and People by paleontologist Kevin Padian of the University of California at Berkeley for the National Center for Science Education's Bookwatch Reviews in 1989 called the book a "wholesale distortion of modern biology", and says that FTE's writers had misrepresented such topics as the Cambrian explosion, the history of birds, and the concept of homology.
PtdIns(3,4)P2 is dephophosphorylated by the phosphatase INPP4B on the 4 position of the inositol ring and by the TPTE (transmembrane phosphatases with tensin homology) family of phosphatases on the 3 position of the inositol ring.
Along with examination of conserved synteny, conserved operon structure, or "Rosetta Stone" domain fusions, comparing phylogenetic profiles is a designated a "post-homology" technique, in that the computation essential to method begins after it is determined which proteins are homologous to which.
The relative SFT of this pair is a differential graded algebra; Ng derives a powerful knot invariant from a combinatorial version of the zero-th degree part of the homology.
It shares sequence homology with mammalian proteins involved in regulating chromatin condensation, for example the human RCC1 gene product.
; Klingenberg, W. (1983) Homology generated by iterated closed geodesics.
While the receptors for VIP (VIRP 1 and 2) and PACAP (ADCYAP1R1) share homology, they differ in their substrate specificities and expression patterns.
The homologues to Ci-VSP in mammals are called Transmembrane phosphatases with tensin homology, or TPTEs.
