The first fundamental representation of $E_{11}$, usually denoted $l_1$, is argued, since (West 04), to contain in its decomposition into representations of $GL(11)$ the representations in which the charges of the M-branes and other BPS states transform.
According to (Nicolai-Fischbacher 03, first three rows of table 2 on p. 72, West 04, Kleinschmidt-West 04) and concisely stated for instance in (West 11, (2.17)), the level decomposition of $l_1$ under $GL(11)$ starts out as so:
Here the $level \leq 2$-truncation happens to coincide with the bosonic body underlying the M-theory super Lie algebra and via the relation of that to BPS charges in 11-dimensional supergravity/M-theory, the direct summands here have been argued to naturally correspond to
level 0: momentum
level 1: M2-brane charge
level 2: M5-brane charge
level 3: dual graviton charge (West 11, section N) (has two components ^{1})
