n.
A gene that is related to another gene in the same organism by descent from a single ancestral gene that was duplicated and that may have a different DNA sequence and biological function.

[Back-formation from paralogous : para- (in reference to the parallel descent of the two genes from a single ancestral gene) + (homo)logous.]

The tandem duplicated paralog aqp1ab was also found in intestinal tissues and showed similar regulation to aqp1aa, although the effect of salinity was less pronounced.
Nevertheless, this paralog is restricted to the apical membrane of flat and elongated epithelial cells (Chauvigne et al., 2013), and thus is similar to the localization of AQP 10 in rat efferent ducts (Hermo et al., 2004).
ZP domain proteins in the abalone egg coat include a paralog of VERL under positive selection that binds lysin and 18-kDa sperm proteins.
EF484875-EF484878), signatures matching these sites could not be assigned to either paralog. The 140 unique signatures comprise 45 perfect 17-bp matches to one or both of the C.
The most informative transcription factors are those that are used repeatedly in the course of vertebrate hematopoietic and immune processes, especially when this applies across vertebrate paralog groups.
ABR is a regulator of the RHO family of small GTPases, signaling proteins involved in cytosketal dynamics, and a paralog of the BCR (BCR activator of RhoGEF and GTPase) gene.
The company added that BLU-554 (CS3008) is an oral, potent highly selective and irreversible inhibitor of FGFR4, with a precise selectivity for FGFR4 that spares the paralog kinases FGFR1, FGFR2 and FGFR3.
CHD5, a brain-specific paralog of Mi2 chromatin remodeling enzymes, regulates expression of neuronal genes.
Aplysianin-A is a paralog of escapin, found in the albumen gland and egg masses of Aplysia californica (Cummins et al., 2004); and orthologs of aplysianin-A are present in Aplysia kurodai (Jimbo et al., 2003).
On the other hand, the domain DUF1088 (domain of unknown function 1088) is shared only by LRBA and its paralog neurobeachin, which may indicate specific functions of these two proteins not shared by other members of the BDCP.
