Gene Snapshot
Macroglobulin complement-related (Mcr) encodes a transmembrane protein of the conserved thioester-containing protein (TEP) superfamily including macroglobulins and complement proteins. It is a core component of septate junctions, which provide an essential paracellular barrier to epithelia. [Date last reviewed: 2019-03-21]

Additional Descriptive Data

Mcr expression is detected in plasmatocytes and in all imaginal discs in larvae. In adults it is observed in the proventriculus, in the crop epithelium and in the epidermis underlying the cuticle in the abodomen but only on the ventral side. Expression is also detected in the mesothoracic phragma, the structure found at the border between thorax and abdomen and to which flight muscles are attached posteriorly.

    Additional comments

    E(br)155 comprises two closely linked mutations corresponding to SP1070 and an anonymous gene in region 26.

    Other Comments

    Mcr is required cell autonomously for the correct membrane localisation of several septate junction components and is required for epithelial barrier formation.

    Mcr is required cell-autonomously for septate junction organisation in embryonic epithelia and larval wing imaginal discs and is required for paracellular barrier function.

    S2 cells treated with dsRNA generated against this gene show reduced phagocytosis of Candida albicans compared to untreated cells. However, the dsRNA treatment does not affect phagocytosis of either Escherichia coli, Staphylococcus aureus or latex beads.

    P-element insertions P{lacW}Trf1 and P{lacW}Trf2 (which lie within 50bp of each other at 28D--28E) map approximately 3kb proximal to 3' end of Mcr transcription unit.

    Transcription unit defined as part of a molecular analysis of Trf.
