Focus on molecules: heparanase.
Heparanase (NP_001092010) is a heparin-binding endo-bD-glucuronidase expressed by normal lacrimal gland (GEO Profiles: GDS1361), corneal epithelia (Berk et al., 2004), retinal pigment epithelium/choroid, lens (NEIBank) and some non-ocular tissues. Heparanase is over-expressed in essentially all human tumors examined. Western blotting suggests that heparanase is a constituent of normal tears (Ma...
متن کاملFocus on molecules: rootletin.
Rootletin (accession number NP_742120) is a large coiled coil protein initially identified as a structural component of the ciliary rootlet (Yang et al., 2002). Its formal designation (ciliary rootlet coiled-coil, rootletin), as listed in most databases, reflects these two known aspects of the protein. The murine rootletin comprises 2009 amino acid residues and has a calculated molecular weight...
متن کاملFocus on molecules: sulfotyrosine.
Besides being a precursor for neurotransmitters, hormones and melanin, tyrosine is a non-essential amino acid that is utilized by the eukaryotic cell to synthesize proteins. Once incorporated into proteins, tyrosine can be post-translationally modified by virtue of its side chain hydroxyl group by nitration, phosphorylation and sulfation. While nitrotyrosine is synthesized through a nonenzymati...
متن کاملFocus on molecules: lacritin.
Lacritin is a 12.3 kDa secreted tear protein in human (accession Q9GZZ8 [Genpept; UniProt; Sanghi et al., 2001]) and non-human primates. It consists of 119 aa after removal of the signal peptide (SP; Fig. 1) and has a predicted isoelectric point (pI ) of 5. Predicted values for secreted lacritin in non-human primates include the following: 12.2 kDa and pI of 5 (Chlorocebus aethiops), 12.3 kDa a...
متن کاملInteraction of tear lipocalin with lysozyme and lactoferrin.
The interaction of human tear lipocalin with lysozyme and lactoferrin was studied by electron paramagnetic resonance (EPR) spectroscopy. TL mutants I98C and F99C were spin labeled with MTSL and its derivative. The spectra demonstrated that at sites C98 and C99 the mobility of the nitroxides was reduced in the presence of lysozyme, lactoferrin, but not albumin. The reduced mobility was manifeste...
