What's a GeneRIF?

Changes in the low-energy absorption/emission band of Lhca4, which is well separated from the bulk absorption, are examined.
Title: From red to blue to far-red in Lhca4: how does the protein modulate the spectral properties of the pigments?
Data indicate that Lhca4 exists in multiple conformations.
Title: Photosystem I light-harvesting complex Lhca4 adopts multiple conformations: Red forms and excited-state quenching are mutually exclusive.
the binding of Lhca1/4 and Lhca2/3 dimers to the core is not interdependent, although weak binding of Lhca2/3 to the core is stabilized by the presence of Lhca4.
Title: The role of Lhca complexes in the supramolecular organization of higher plant photosystem I.
target for STN7-dependent phosphorylation under extreme redox conditions
Title: Impaired photosystem I oxidation induces STN7-dependent phosphorylation of the light-harvesting complex I protein Lhca4 in Arabidopsis thaliana.
analysis of pigment-pigment interactions between nearest neighboring chromophores in Lhca4 antenna complex showed that the low energy spectral form originates from an interaction involving chlorophylls A5 and B5(Lhca4)
Title: Pigment-pigment interactions in Lhca4 antenna complex of higher plants photosystem I.
