Protein Family Models

AvrLm4-7 is found in Leptosphaeria maculans, an ascomycete fungus in the dothideomycete group which is responsible for stem canker (blackleg) of Brassica napus (oilseed rape, OSR) and other crucifers. AvrLm4-7 is one of six avirulence genes which encodes a small secreted protein strongly over-expressed at the onset of plant infection. This gene confers a dual recognition specificity by two distinct resistance genes of OSR, Rlm4 and Rlm7 and loss of AvrLm4 avirulence was demonstrated to be associated with a strong fitness cost. Structure and functional analysis of AvrLm4-7 protein show that it contains the motifs RAWG and RYRE, part of a well-structured protein region held together by disulfide bridges. Mutations in the RAWG motif or in the RYRE motif (especially mutations in both motifs) almost abolished the translocation of AvrLm4-7 into cells. Furthermore, loss of recognition of AvrLm4-7 by Rlm4 is caused by the mutation of a single glycine to an arginine residue located in a loop of the protein [1]. [1]. 26082394.

This domain family is found in eukaryotes, and is typically between 113 and 125 amino acids in length. The family is found in association with Pfam:PF03441, Pfam:PF00875. Cryptochromes are blue/ultraviolet-A light sensing photoreceptors involved in regulating various growth and developmental responses in plants. [1]. 16531484.

This family consists of a number of cysteine rich SLR1 binding pollen coat like proteins. Adhesion of pollen grains to the stigmatic surface is a critical step during sexual reproduction in plants. In Brassica, S locus-related glycoprotein 1 (SLR1), a stigma-specific protein belonging to the S gene family of proteins, has been shown to be involved in this step. SLR1-BP specifically binds SLR1 with high affinity. The SLR1-BP gene is specifically expressed in pollen at late stages of development and is a member of the class A pollen coat protein (PCP) family, which includes PCP-A1, an SLG (S locus glycoprotein)-binding protein [1].

This family consists of several plant tapetum specific proteins. Members of this family are found in Arabidopsis thaliana, Brassica napus and Sinapis alba. Members of this family may be involved in sporopollenin formation and/or deposition [1]. [1]. 7764317. The proteins encoded by two tapetum-specific transcripts, Sa. tap35 and Sa tap44, from Sinapis alba L. are localized in the. exine cell wall layer of developing microspores..

This family consists of several Plant self-incompatibility response (SCRL) proteins. The male component of the self-incompatibility response in Brassica has been shown to be encoded by the S locus cysteine-rich gene (SCR). SCR is related, at the sequence level, to the pollen coat protein (PCP) gene family whose members encode small, cysteine-rich proteins located in the proteo-lipidic surface layer (tryphine) of Brassica pollen grains [1]. [1]. 11437247. Two large Arabidopsis thaliana gene families are homologous to. the Brassica gene superfamily that encodes pollen coat proteins. and the male component of the self-incompatibility response..

The BURP domain is found at the C-terminus of several different plant proteins. It was named after the proteins in which it was first identified: the BNM2 clone-derived protein from Brassica napus Swiss:O65009; USPs and USP-like proteins Swiss:P21746 Swiss:P21747 Swiss:Q06765 Swiss:O24482; RD22 from Arabidopsis thaliana Swiss:Q08298; and PG1beta from Lycopersicon esculentum Swiss:Q40161. This domain is around 230 amino acid residues long. It possesses the following conserved features: two phenylalanine residues at its N-terminus; two cysteine residues; and four repeated cysteine-histidine motifs, arranged as: CH-X(10)-CH-X(25-27)-CH-X(25-26)-CH, where X can be any amino acid [1]. The function of this domain is unknown. [1]. 9790599. A conserved BURP domain defines a novel group of plant proteins. with unusual primary structures..

In Brassicaceae, self-incompatible plants have a self/non-self recognition system. This is sporophytically controlled by multiple alleles at a single locus (S). S-locus glycoproteins, as well as S-receptor kinases, are in linkage with the S-alleles [1]. This region is inferred to be a domain due to it having other domains adjacent to it. [1]. 7672580.
